142343-72-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142343-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,3,4 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 142343-72:
(8*1)+(7*4)+(6*2)+(5*3)+(4*4)+(3*3)+(2*7)+(1*2)=104
104 % 10 = 4
So 142343-72-4 is a valid CAS Registry Number.
