Check Digit Verification of cas no

The CAS Registry Mumber 102183-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,1,8 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 102183-91:
(8*1)+(7*0)+(6*2)+(5*1)+(4*8)+(3*3)+(2*9)+(1*1)=85
85 % 10 = 5
So 102183-91-5 is a valid CAS Registry Number.

Sodium fluoride as an efficient catalyst for the synthesis of 2,4-disubstituted-1,3-thiazoles and selenazoles at ambient temperature

Banothu, Janardhan,Vaarla, Krishnaiah,Bavantula, Rajitha,Crooks, Peter A.

, p. 172 - 175 (2014)

Sodium fluoride was found to be a simple, mild and efficient catalyst for the synthesis of 2,4-disubstituted 1,3-thiazoles and selenazoles utilizing phenacyl bromides/3-(2-bromoacetyl)-2H-chromen-2-one and thiourea/ phenylthiourea/selenourea in aqueous methanol at ambient temperature. Analytically pure products are formed within 1-3 min in excellent yields.

Green approach: An efficient synthesis of 2,4-disubstituted-1,3-thiazoles and selenazoles in aqueous medium under ultrasonic irradiation

Ramesh, Gondru,Janardhan, Banothu,Rajitha, Bavantula

, p. 8099 - 8109 (2015/04/16)

An efficient and rapid procedure for the synthesis of 2,4-disubstituted-1,3-thiazoles and selenazoles has been described by the reaction of α-bromoketones with thiourea, phenylthiourea and selenourea at ambient temperature in aqueous medium under ultrasonic irradiation. Analytically pure products were formed within 10-60 s in excellent yields. The advantageous features of this non-conventional methodology over conventional methods are the operational simplicity, easy handling, yield-enhancing, time-reducing, mild reaction conditions and no by-product production.

Lipase and deep eutectic mixture catalyzed efficient synthesis of thiazoles in water at room temperature

Lobo, Hyacintha Rennet,Singh, Balvant Shyam,Shankarling, Ganapati Subray

, p. 1369 - 1375 (2013/01/15)

Lipase bio-catalyst or ammonium based deep eutectic mixture efficiently catalyzed aqueous phase synthesis of methyl-thiazole and amino-thiazole derivatives. The simple ammonium deep eutectic catalyst, easily synthesized from choline chloride and urea, is inexpensive, recyclable and bio-degradable, making it suitable for industrial applications.
