127143-08-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127143-08-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,1,4 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127143-08:
(8*1)+(7*2)+(6*7)+(5*1)+(4*4)+(3*3)+(2*0)+(1*8)=102
102 % 10 = 2
So 127143-08-2 is a valid CAS Registry Number.
