Check Digit Verification of cas no
The CAS Registry Mumber 77172-72-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,7 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77172-72:
(7*7)+(6*7)+(5*1)+(4*7)+(3*2)+(2*7)+(1*2)=146
146 % 10 = 6
So 77172-72-6 is a valid CAS Registry Number.
