Check Digit Verification of cas no

The CAS Registry Mumber 638140-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,8,1,4 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 638140-91:
(8*6)+(7*3)+(6*8)+(5*1)+(4*4)+(3*0)+(2*9)+(1*1)=157
157 % 10 = 7
So 638140-91-7 is a valid CAS Registry Number.
