Check Digit Verification of cas no

The CAS Registry Mumber 91344-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,3,4 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91344-68:
(7*9)+(6*1)+(5*3)+(4*4)+(3*4)+(2*6)+(1*8)=132
132 % 10 = 2
So 91344-68-2 is a valid CAS Registry Number.
