Check Digit Verification of cas no

The CAS Registry Mumber 446874-39-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,6,8,7 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 446874-39:
(8*4)+(7*4)+(6*6)+(5*8)+(4*7)+(3*4)+(2*3)+(1*9)=191
191 % 10 = 1
So 446874-39-1 is a valid CAS Registry Number.
