144899-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144899-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,8,9 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 144899-91:
(8*1)+(7*4)+(6*4)+(5*8)+(4*9)+(3*9)+(2*9)+(1*1)=182
182 % 10 = 2
So 144899-91-2 is a valid CAS Registry Number.
