Check Digit Verification of cas no

The CAS Registry Mumber 1421357-48-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,3,5 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1421357-48:
(9*1)+(8*4)+(7*2)+(6*1)+(5*3)+(4*5)+(3*7)+(2*4)+(1*8)=133
133 % 10 = 3
So 1421357-48-3 is a valid CAS Registry Number.
