Check Digit Verification of cas no

The CAS Registry Mumber 70932-71-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,9,3 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 70932-71:
(7*7)+(6*0)+(5*9)+(4*3)+(3*2)+(2*7)+(1*1)=127
127 % 10 = 7
So 70932-71-7 is a valid CAS Registry Number.
