Check Digit Verification of cas no

The CAS Registry Mumber 193621-90-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,6,2 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 193621-90:
(8*1)+(7*9)+(6*3)+(5*6)+(4*2)+(3*1)+(2*9)+(1*0)=148
148 % 10 = 8
So 193621-90-8 is a valid CAS Registry Number.
