104321-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104321-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,3,2 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 104321-89:
(8*1)+(7*0)+(6*4)+(5*3)+(4*2)+(3*1)+(2*8)+(1*9)=83
83 % 10 = 3
So 104321-89-3 is a valid CAS Registry Number.
