Check Digit Verification of cas no

The CAS Registry Mumber 5042-05-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,4 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5042-05:
(6*5)+(5*0)+(4*4)+(3*2)+(2*0)+(1*5)=57
57 % 10 = 7
So 5042-05-7 is a valid CAS Registry Number.
