Check Digit Verification of cas no

The CAS Registry Mumber 52954-44-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,9,5 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 52954-44:
(7*5)+(6*2)+(5*9)+(4*5)+(3*4)+(2*4)+(1*4)=136
136 % 10 = 6
So 52954-44-6 is a valid CAS Registry Number.
