Check Digit Verification of cas no

The CAS Registry Mumber 874899-29-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,8,9 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 874899-29:
(8*8)+(7*7)+(6*4)+(5*8)+(4*9)+(3*9)+(2*2)+(1*9)=253
253 % 10 = 3
So 874899-29-3 is a valid CAS Registry Number.
