Check Digit Verification of cas no

The CAS Registry Mumber 1202-19-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,0 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1202-19:
(6*1)+(5*2)+(4*0)+(3*2)+(2*1)+(1*9)=33
33 % 10 = 3
So 1202-19-3 is a valid CAS Registry Number.
