Check Digit Verification of cas no

The CAS Registry Mumber 144882-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,8,8 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 144882-91:
(8*1)+(7*4)+(6*4)+(5*8)+(4*8)+(3*2)+(2*9)+(1*1)=157
157 % 10 = 7
So 144882-91-7 is a valid CAS Registry Number.
