271799-03-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 271799-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,1,7,9 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 271799-03:
(8*2)+(7*7)+(6*1)+(5*7)+(4*9)+(3*9)+(2*0)+(1*3)=172
172 % 10 = 2
So 271799-03-2 is a valid CAS Registry Number.
