Check Digit Verification of cas no

The CAS Registry Mumber 71189-74-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,1,8 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 71189-74:
(7*7)+(6*1)+(5*1)+(4*8)+(3*9)+(2*7)+(1*4)=137
137 % 10 = 7
So 71189-74-7 is a valid CAS Registry Number.
