Check Digit Verification of cas no

The CAS Registry Mumber 77204-48-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,0 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77204-48:
(7*7)+(6*7)+(5*2)+(4*0)+(3*4)+(2*4)+(1*8)=129
129 % 10 = 9
So 77204-48-9 is a valid CAS Registry Number.

The Synthetic Utility of Heteroaromatic Azido Compounds. Part VI. Preparation of some 1H-1,2,3-Triazolothienopyrimidines

Westerlund, Christer

, p. 1765 - 1769 (2007/10/02)

Some 1,2,3-triazolothienopyrimidines have been prepared by the reaction of active methylene nitriles with 3-azido-2-substituted thiophenes.Thus, for example the 3-carboxy derivative 5 was prepared by condensation of 3-azido-2-formylthiophene
