1029441-31-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1029441-31-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,9,4,4 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1029441-31:
(9*1)+(8*0)+(7*2)+(6*9)+(5*4)+(4*4)+(3*1)+(2*3)+(1*1)=123
123 % 10 = 3
So 1029441-31-3 is a valid CAS Registry Number.
