Check Digit Verification of cas no

The CAS Registry Mumber 819799-41-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,9,7,9 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 819799-41:
(8*8)+(7*1)+(6*9)+(5*7)+(4*9)+(3*9)+(2*4)+(1*1)=232
232 % 10 = 2
So 819799-41-2 is a valid CAS Registry Number.
