Check Digit Verification of cas no

The CAS Registry Mumber 109921-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,2 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109921-41:
(8*1)+(7*0)+(6*9)+(5*9)+(4*2)+(3*1)+(2*4)+(1*1)=127
127 % 10 = 7
So 109921-41-7 is a valid CAS Registry Number.
