Check Digit Verification of cas no

The CAS Registry Mumber 2742-70-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,4 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2742-70:
(6*2)+(5*7)+(4*4)+(3*2)+(2*7)+(1*0)=83
83 % 10 = 3
So 2742-70-3 is a valid CAS Registry Number.
