Check Digit Verification of cas no

The CAS Registry Mumber 1257651-49-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,6,5 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1257651-49:
(9*1)+(8*2)+(7*5)+(6*7)+(5*6)+(4*5)+(3*1)+(2*4)+(1*9)=172
172 % 10 = 2
So 1257651-49-2 is a valid CAS Registry Number.
