Check Digit Verification of cas no

The CAS Registry Mumber 749913-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,9,9,1 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 749913-89:
(8*7)+(7*4)+(6*9)+(5*9)+(4*1)+(3*3)+(2*8)+(1*9)=221
221 % 10 = 1
So 749913-89-1 is a valid CAS Registry Number.
