1174271-28-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1174271-28-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,4,2,7 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1174271-28:
(9*1)+(8*1)+(7*7)+(6*4)+(5*2)+(4*7)+(3*1)+(2*2)+(1*8)=143
143 % 10 = 3
So 1174271-28-3 is a valid CAS Registry Number.
