Check Digit Verification of cas no

The CAS Registry Mumber 112672-64-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,6,7 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 112672-64:
(8*1)+(7*1)+(6*2)+(5*6)+(4*7)+(3*2)+(2*6)+(1*4)=107
107 % 10 = 7
So 112672-64-7 is a valid CAS Registry Number.
