Check Digit Verification of cas no

The CAS Registry Mumber 77333-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,3 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77333-72:
(7*7)+(6*7)+(5*3)+(4*3)+(3*3)+(2*7)+(1*2)=143
143 % 10 = 3
So 77333-72-3 is a valid CAS Registry Number.
