1434139-83-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1434139-83-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,4,1,3 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1434139-83:
(9*1)+(8*4)+(7*3)+(6*4)+(5*1)+(4*3)+(3*9)+(2*8)+(1*3)=149
149 % 10 = 9
So 1434139-83-9 is a valid CAS Registry Number.
