Check Digit Verification of cas no

The CAS Registry Mumber 70329-36-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,3,2 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 70329-36:
(7*7)+(6*0)+(5*3)+(4*2)+(3*9)+(2*3)+(1*6)=111
111 % 10 = 1
So 70329-36-1 is a valid CAS Registry Number.
