Check Digit Verification of cas no
The CAS Registry Mumber 33719-11-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,7,1 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 33719-11:
(7*3)+(6*3)+(5*7)+(4*1)+(3*9)+(2*1)+(1*1)=108
108 % 10 = 8
So 33719-11-8 is a valid CAS Registry Number.

, (2018/05/16)
The invention discloses a method for preparing a D-biotin bromide intermediate. The method comprises: S1) carrying out a reaction on a compound 3 and a 1-bromo-3-methoxypropane magnesium bromide Grignard reagent to obtain a compound 4; S2) carrying out a reflux dewatering reaction on the compound 4 under the action of p-toluenesulfonic acid to obtain a compound 5; S3) carrying out a hydrogenationreaction on the compound 5 to obtain a compound 6; and S4) carrying out a cyclization reaction on the compound 6 to obtain a bromide intermediate. According to the present invention, the 1-bromo-3-methoxypropane magnesium bromide Grignard reagent is prepared through self-initiation; the method has advantages of mild reaction conditions, simple and safe operation, easy large-scale production and the like; and with the method, the total molar yield of the four steps can achieve more than 75%, the product purity is up to more than 98%, and the inexpensive and easily-available palladium carbon catalyst can be used in the hydrogenation reaction and can be recycled.
