144068-22-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144068-22-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,0,6 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 144068-22:
(8*1)+(7*4)+(6*4)+(5*0)+(4*6)+(3*8)+(2*2)+(1*2)=114
114 % 10 = 4
So 144068-22-4 is a valid CAS Registry Number.
