Check Digit Verification of cas no

The CAS Registry Mumber 99967-80-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,6 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99967-80:
(7*9)+(6*9)+(5*9)+(4*6)+(3*7)+(2*8)+(1*0)=223
223 % 10 = 3
So 99967-80-3 is a valid CAS Registry Number.

Thiazoles from N-Cyanoimidates or 3-Cyanoisoureas and Thioglycolic Acid Derivatives

Ried, Walter,Kuhnt, Dietmar

, p. 780 - 784 (2007/10/02)

Novel thiazoles 3a-g, 4a-d are synthesized from N-cyanoimidates and 3-cyanoisoureas of type 1a-m and thioglycolic acid methyl ester (2a) as well as the amide (2b).The limitations of the reaction are outlined.The products are further converted into thiazolopyrimidines 6a-d and thiazolo-1,2,3-triazinones 7a-c.
