28746-27-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28746-27-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,7,4 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28746-27:
(7*2)+(6*8)+(5*7)+(4*4)+(3*6)+(2*2)+(1*7)=142
142 % 10 = 2
So 28746-27-2 is a valid CAS Registry Number.
