77897-14-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77897-14-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,9 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77897-14:
(7*7)+(6*7)+(5*8)+(4*9)+(3*7)+(2*1)+(1*4)=194
194 % 10 = 4
So 77897-14-4 is a valid CAS Registry Number.
