143660-65-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143660-65-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,6,6 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 143660-65:
(8*1)+(7*4)+(6*3)+(5*6)+(4*6)+(3*0)+(2*6)+(1*5)=125
125 % 10 = 5
So 143660-65-5 is a valid CAS Registry Number.
