Check Digit Verification of cas no

The CAS Registry Mumber 423768-42-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,3,7,6 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 423768-42:
(8*4)+(7*2)+(6*3)+(5*7)+(4*6)+(3*8)+(2*4)+(1*2)=157
157 % 10 = 7
So 423768-42-7 is a valid CAS Registry Number.
