The CAS Registry Mumber 198954-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,9,5 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 198954-23:
(8*1)+(7*9)+(6*8)+(5*9)+(4*5)+(3*4)+(2*2)+(1*3)=203
203 % 10 = 3
So 198954-23-3 is a valid CAS Registry Number.
