Check Digit Verification of cas no

The CAS Registry Mumber 2657-45-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,5 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2657-45:
(6*2)+(5*6)+(4*5)+(3*7)+(2*4)+(1*5)=96
96 % 10 = 6
So 2657-45-6 is a valid CAS Registry Number.
