Check Digit Verification of cas no

The CAS Registry Mumber 87233-13-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,3 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87233-13:
(7*8)+(6*7)+(5*2)+(4*3)+(3*3)+(2*1)+(1*3)=134
134 % 10 = 4
So 87233-13-4 is a valid CAS Registry Number.
