144686-20-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144686-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,6,8 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 144686-20:
(8*1)+(7*4)+(6*4)+(5*6)+(4*8)+(3*6)+(2*2)+(1*0)=144
144 % 10 = 4
So 144686-20-4 is a valid CAS Registry Number.
