Check Digit Verification of cas no

The CAS Registry Mumber 99422-64-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,2 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 99422-64:
(7*9)+(6*9)+(5*4)+(4*2)+(3*2)+(2*6)+(1*4)=167
167 % 10 = 7
So 99422-64-7 is a valid CAS Registry Number.
