104831-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104831-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,8,3 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 104831-21:
(8*1)+(7*0)+(6*4)+(5*8)+(4*3)+(3*1)+(2*2)+(1*1)=92
92 % 10 = 2
So 104831-21-2 is a valid CAS Registry Number.
