The CAS Registry Mumber 121649-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,4 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 121649-94:
(8*1)+(7*2)+(6*1)+(5*6)+(4*4)+(3*9)+(2*9)+(1*4)=123
123 % 10 = 3
So 121649-94-3 is a valid CAS Registry Number.
