144341-01-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144341-01-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,3,4 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 144341-01:
(8*1)+(7*4)+(6*4)+(5*3)+(4*4)+(3*1)+(2*0)+(1*1)=95
95 % 10 = 5
So 144341-01-5 is a valid CAS Registry Number.
