Check Digit Verification of cas no

The CAS Registry Mumber 74255-79-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,5 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74255-79:
(7*7)+(6*4)+(5*2)+(4*5)+(3*5)+(2*7)+(1*9)=141
141 % 10 = 1
So 74255-79-1 is a valid CAS Registry Number.
