Check Digit Verification of cas no
The CAS Registry Mumber 77517-76-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,1 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 77517-76:
(7*7)+(6*7)+(5*5)+(4*1)+(3*7)+(2*7)+(1*6)=161
161 % 10 = 1
So 77517-76-1 is a valid CAS Registry Number.
