Check Digit Verification of cas no

The CAS Registry Mumber 123742-56-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,4 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 123742-56:
(8*1)+(7*2)+(6*3)+(5*7)+(4*4)+(3*2)+(2*5)+(1*6)=113
113 % 10 = 3
So 123742-56-3 is a valid CAS Registry Number.
