104430-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104430-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,4,3 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 104430-40:
(8*1)+(7*0)+(6*4)+(5*4)+(4*3)+(3*0)+(2*4)+(1*0)=72
72 % 10 = 2
So 104430-40-2 is a valid CAS Registry Number.
