5Check Digit Verification of cas no
The CAS Registry Mumber 77538-14-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,3 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.Calculate Digit Verification of CAS Registry Number 77538-14:
(7*7)+(6*7)+(5*5)+(4*3)+(3*8)+(2*1)+(1*4)=158
158 % 10 = 8
So 77538-14-8 is a valid CAS Registry Number.
