Check Digit Verification of cas no

The CAS Registry Mumber 81344-59-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,4 and 4 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81344-59:
(7*8)+(6*1)+(5*3)+(4*4)+(3*4)+(2*5)+(1*9)=124
124 % 10 = 4
So 81344-59-4 is a valid CAS Registry Number.
