Check Digit Verification of cas no

The CAS Registry Mumber 1402-35-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,0 and 2 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1402-35:
(6*1)+(5*4)+(4*0)+(3*2)+(2*3)+(1*5)=43
43 % 10 = 3
So 1402-35-3 is a valid CAS Registry Number.
