87961-20-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87961-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,9,6 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87961-20:
(7*8)+(6*7)+(5*9)+(4*6)+(3*1)+(2*2)+(1*0)=174
174 % 10 = 4
So 87961-20-4 is a valid CAS Registry Number.

Oxidation of Substituted 1-Hetera-4-cyclohexanols by N-Bromsuccinimide

Jambulingam, M.,Nanjappan, P.,Natarajan, K.,Ramalingam, K.

, p. 390 - 394 (2007/10/02)

The rates of NBS oxidation of some substituted 1-hetera-4-cyclohexanols have been measured at 50 deg in 80percent acetic acid-20percent water (v/v).The primary kinetic isotope effect is suggestive of the involvement of C-H or C-D bond of the hydroxy beari
