Check Digit Verification of cas no

The CAS Registry Mumber 72740-33-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,7,4 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 72740-33:
(7*7)+(6*2)+(5*7)+(4*4)+(3*0)+(2*3)+(1*3)=121
121 % 10 = 1
So 72740-33-1 is a valid CAS Registry Number.
