143661-86-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143661-86-3 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 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 143661-86:
(8*1)+(7*4)+(6*3)+(5*6)+(4*6)+(3*1)+(2*8)+(1*6)=133
133 % 10 = 3
So 143661-86-3 is a valid CAS Registry Number.
