1168-28-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1168-28-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,6 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1168-28:
(6*1)+(5*1)+(4*6)+(3*8)+(2*2)+(1*8)=71
71 % 10 = 1
So 1168-28-1 is a valid CAS Registry Number.
