142434-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142434-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,4,3 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 142434-69:
(8*1)+(7*4)+(6*2)+(5*4)+(4*3)+(3*4)+(2*6)+(1*9)=113
113 % 10 = 3
So 142434-69-3 is a valid CAS Registry Number.
