Check Digit Verification of cas no

The CAS Registry Mumber 491876-41-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,1,8,7 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 491876-41:
(8*4)+(7*9)+(6*1)+(5*8)+(4*7)+(3*6)+(2*4)+(1*1)=196
196 % 10 = 6
So 491876-41-6 is a valid CAS Registry Number.
