Check Digit Verification of cas no

The CAS Registry Mumber 128095-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,9 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128095-03:
(8*1)+(7*2)+(6*8)+(5*0)+(4*9)+(3*5)+(2*0)+(1*3)=124
124 % 10 = 4
So 128095-03-4 is a valid CAS Registry Number.

Alkylation of 3,5-Dimethylisothiazole. A Regioselective Synthesis of 5-Alkyl-3-methylisothiazoles

Alberola, Angel,Andres, Celia,Casado, Jose L.,Gonzalez, Alfonso,Pedrosa, Rafael

, p. 617 - 624 (2007/10/02)

3,5-Dimethylisothiazole reacts sequentially with lithiumdiisopropylamide (molar ratio 1:1) and alkyl halides (in excess) affording 5-alkyl-3-methylisothiazoles in excellent yields.When a two-fold excess of base is used, a mixture of 5-monoalkylated and 3,5-dialkylated products is obtained.Sodium amide was tried as deprotonating agent, but the yield in final products was lower.
