16222-34-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 16222-34-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,2 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 16222-34:
(7*1)+(6*6)+(5*2)+(4*2)+(3*2)+(2*3)+(1*4)=77
77 % 10 = 7
So 16222-34-7 is a valid CAS Registry Number.

Charge-Enhanced Acidity and Catalyst Activation
Samet, Masoud,Buhle, Jordan,Zhou, Yunwen,Kass, Steven R.
, p. 4678 - 4680 (2015)
Acidities are commonly measured in polar solvents but catalytic reactions are typically carried out in nonpolar media. IR spectra of a series of phenols in CCl4 and 1% CD3CN/CCl4 provide relative acidities. Nonprotonated c
