144658-71-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144658-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,6,5 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 144658-71:
(8*1)+(7*4)+(6*4)+(5*6)+(4*5)+(3*8)+(2*7)+(1*1)=149
149 % 10 = 9
So 144658-71-9 is a valid CAS Registry Number.
