143729-34-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143729-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,2 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 143729-34:
(8*1)+(7*4)+(6*3)+(5*7)+(4*2)+(3*9)+(2*3)+(1*4)=134
134 % 10 = 4
So 143729-34-4 is a valid CAS Registry Number.
