The CAS Registry Mumber 199392-32-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,3,9 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 199392-32:
(8*1)+(7*9)+(6*9)+(5*3)+(4*9)+(3*2)+(2*3)+(1*2)=190
190 % 10 = 0
So 199392-32-0 is a valid CAS Registry Number.
