143771-08-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143771-08-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,7 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 143771-08:
(8*1)+(7*4)+(6*3)+(5*7)+(4*7)+(3*1)+(2*0)+(1*8)=128
128 % 10 = 8
So 143771-08-8 is a valid CAS Registry Number.
