Check Digit Verification of cas no

The CAS Registry Mumber 71629-79-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,6,2 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 71629-79:
(7*7)+(6*1)+(5*6)+(4*2)+(3*9)+(2*7)+(1*9)=143
143 % 10 = 3
So 71629-79-3 is a valid CAS Registry Number.
