Check Digit Verification of cas no

The CAS Registry Mumber 619336-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,9,3,3 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 619336-91:
(8*6)+(7*1)+(6*9)+(5*3)+(4*3)+(3*6)+(2*9)+(1*1)=173
173 % 10 = 3
So 619336-91-3 is a valid CAS Registry Number.
