Check Digit Verification of cas no

The CAS Registry Mumber 2959-76-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,5 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2959-76:
(6*2)+(5*9)+(4*5)+(3*9)+(2*7)+(1*6)=124
124 % 10 = 4
So 2959-76-4 is a valid CAS Registry Number.
