Check Digit Verification of cas no

The CAS Registry Mumber 1254472-49-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,4,7 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1254472-49:
(9*1)+(8*2)+(7*5)+(6*4)+(5*4)+(4*7)+(3*2)+(2*4)+(1*9)=155
155 % 10 = 5
So 1254472-49-5 is a valid CAS Registry Number.
