Check Digit Verification of cas no
The CAS Registry Mumber 876373-32-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,6,3,7 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 876373-32:
(8*8)+(7*7)+(6*6)+(5*3)+(4*7)+(3*3)+(2*3)+(1*2)=209
209 % 10 = 9
So 876373-32-9 is a valid CAS Registry Number.

Microwave-assisted synthesis of 8-mercapto-3-methyl-7-alkyl xanthines - An improved method
Zhang, Lei,Zhang, Y. John
, p. 775 - 778 (2006)
A microwave-assisted synthetic method to prepare novel 8-mercapto-3-methyl- 7-alkyl xanthine compounds is reported. Compared to conventional synthetic route, the new method significantly shortened synthetic steps and reaction time.
