Check Digit Verification of cas no

The CAS Registry Mumber 88891-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,8,9 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 88891-50:
(7*8)+(6*8)+(5*8)+(4*9)+(3*1)+(2*5)+(1*0)=193
193 % 10 = 3
So 88891-50-3 is a valid CAS Registry Number.
