Check Digit Verification of cas no

The CAS Registry Mumber 6420-39-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6420-39:
(6*6)+(5*4)+(4*2)+(3*0)+(2*3)+(1*9)=79
79 % 10 = 9
So 6420-39-9 is a valid CAS Registry Number.
