142452-44-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142452-44-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,4,5 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142452-44:
(8*1)+(7*4)+(6*2)+(5*4)+(4*5)+(3*2)+(2*4)+(1*4)=106
106 % 10 = 6
So 142452-44-6 is a valid CAS Registry Number.
