Check Digit Verification of cas no

The CAS Registry Mumber 77101-36-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,0 and 1 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 77101-36:
(7*7)+(6*7)+(5*1)+(4*0)+(3*1)+(2*3)+(1*6)=111
111 % 10 = 1
So 77101-36-1 is a valid CAS Registry Number.
