Check Digit Verification of cas no

The CAS Registry Mumber 874796-30-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,7,9 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 874796-30:
(8*8)+(7*7)+(6*4)+(5*7)+(4*9)+(3*6)+(2*3)+(1*0)=232
232 % 10 = 2
So 874796-30-2 is a valid CAS Registry Number.
