Check Digit Verification of cas no

The CAS Registry Mumber 199169-42-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,1,6 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 199169-42:
(8*1)+(7*9)+(6*9)+(5*1)+(4*6)+(3*9)+(2*4)+(1*2)=191
191 % 10 = 1
So 199169-42-1 is a valid CAS Registry Number.
