Check Digit Verification of cas no

The CAS Registry Mumber 1256493-72-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,4,9 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1256493-72:
(9*1)+(8*2)+(7*5)+(6*6)+(5*4)+(4*9)+(3*3)+(2*7)+(1*2)=177
177 % 10 = 7
So 1256493-72-7 is a valid CAS Registry Number.
