Check Digit Verification of cas no

The CAS Registry Mumber 77627-13-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,2 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77627-13:
(7*7)+(6*7)+(5*6)+(4*2)+(3*7)+(2*1)+(1*3)=155
155 % 10 = 5
So 77627-13-5 is a valid CAS Registry Number.
