Check Digit Verification of cas no

The CAS Registry Mumber 197302-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,3,0 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 197302-33:
(8*1)+(7*9)+(6*7)+(5*3)+(4*0)+(3*2)+(2*3)+(1*3)=143
143 % 10 = 3
So 197302-33-3 is a valid CAS Registry Number.
