431902-11-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 431902-11-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,1,9,0 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 431902-11:
(8*4)+(7*3)+(6*1)+(5*9)+(4*0)+(3*2)+(2*1)+(1*1)=113
113 % 10 = 3
So 431902-11-3 is a valid CAS Registry Number.
