25837-82-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25837-82-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,3 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 25837-82:
(7*2)+(6*5)+(5*8)+(4*3)+(3*7)+(2*8)+(1*2)=135
135 % 10 = 5
So 25837-82-5 is a valid CAS Registry Number.

Higgins, Eleanor M.,Sherwood, Jennifer A.,Lindsay, Anita G.,Armstrong, James,Massey, Richard S.,Alder, Roger W.,O'Donoghue, Annmarie C.
, p. 1559 - 1561 (2011)
pKa values of 19.8-28.2 are reported for the conjugate acids of a large series of NHCs in water. The effects of ring size, N-substituent and C(4)-C(5) saturation on pKa are discussed.
