Check Digit Verification of cas no

The CAS Registry Mumber 42427-36-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,4,2 and 7 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 42427-36:
(7*4)+(6*2)+(5*4)+(4*2)+(3*7)+(2*3)+(1*6)=101
101 % 10 = 1
So 42427-36-1 is a valid CAS Registry Number.
