Check Digit Verification of cas no

The CAS Registry Mumber 2957-40-6 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 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2957-40:
(6*2)+(5*9)+(4*5)+(3*7)+(2*4)+(1*0)=106
106 % 10 = 6
So 2957-40-6 is a valid CAS Registry Number.
