Check Digit Verification of cas no

The CAS Registry Mumber 952657-51-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,2,6,5 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 952657-51:
(8*9)+(7*5)+(6*2)+(5*6)+(4*5)+(3*7)+(2*5)+(1*1)=201
201 % 10 = 1
So 952657-51-1 is a valid CAS Registry Number.
