Check Digit Verification of cas no

The CAS Registry Mumber 1458733-83-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,8,7,3 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1458733-83:
(9*1)+(8*4)+(7*5)+(6*8)+(5*7)+(4*3)+(3*3)+(2*8)+(1*3)=199
199 % 10 = 9
So 1458733-83-9 is a valid CAS Registry Number.
