Check Digit Verification of cas no

The CAS Registry Mumber 157495-51-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,4,9 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 157495-51:
(8*1)+(7*5)+(6*7)+(5*4)+(4*9)+(3*5)+(2*5)+(1*1)=167
167 % 10 = 7
So 157495-51-7 is a valid CAS Registry Number.
