The CAS Registry Mumber 198420-11-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,4,2 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 198420-11:
(8*1)+(7*9)+(6*8)+(5*4)+(4*2)+(3*0)+(2*1)+(1*1)=150
150 % 10 = 0
So 198420-11-0 is a valid CAS Registry Number.
