127099-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127099-71-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,9 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 127099-71:
(8*1)+(7*2)+(6*7)+(5*0)+(4*9)+(3*9)+(2*7)+(1*1)=142
142 % 10 = 2
So 127099-71-2 is a valid CAS Registry Number.
