143644-45-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143644-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,6,4 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 143644-45:
(8*1)+(7*4)+(6*3)+(5*6)+(4*4)+(3*4)+(2*4)+(1*5)=125
125 % 10 = 5
So 143644-45-5 is a valid CAS Registry Number.
