Check Digit Verification of cas no
The CAS Registry Mumber 77954-04-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,5 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77954-04:
(7*7)+(6*7)+(5*9)+(4*5)+(3*4)+(2*0)+(1*4)=172
172 % 10 = 2
So 77954-04-2 is a valid CAS Registry Number.
