Check Digit Verification of cas no

The CAS Registry Mumber 869377-32-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,3,7 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 869377-32:
(8*8)+(7*6)+(6*9)+(5*3)+(4*7)+(3*7)+(2*3)+(1*2)=232
232 % 10 = 2
So 869377-32-2 is a valid CAS Registry Number.
