17759-28-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 17759-28-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,7,5 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 17759-28:
(7*1)+(6*7)+(5*7)+(4*5)+(3*9)+(2*2)+(1*8)=143
143 % 10 = 3
So 17759-28-3 is a valid CAS Registry Number.
