Check Digit Verification of cas no

The CAS Registry Mumber 1257653-19-2 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 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1257653-19:
(9*1)+(8*2)+(7*5)+(6*7)+(5*6)+(4*5)+(3*3)+(2*1)+(1*9)=172
172 % 10 = 2
So 1257653-19-2 is a valid CAS Registry Number.
