Check Digit Verification of cas no

The CAS Registry Mumber 187401-91-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,4,0 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 187401-91:
(8*1)+(7*8)+(6*7)+(5*4)+(4*0)+(3*1)+(2*9)+(1*1)=148
148 % 10 = 8
So 187401-91-8 is a valid CAS Registry Number.
