142144-55-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142144-55-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,1,4 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142144-55:
(8*1)+(7*4)+(6*2)+(5*1)+(4*4)+(3*4)+(2*5)+(1*5)=96
96 % 10 = 6
So 142144-55-6 is a valid CAS Registry Number.
