Check Digit Verification of cas no

The CAS Registry Mumber 4672-40-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,7 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4672-40:
(6*4)+(5*6)+(4*7)+(3*2)+(2*4)+(1*0)=96
96 % 10 = 6
So 4672-40-6 is a valid CAS Registry Number.
