73838-65-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73838-65-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,8,3 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 73838-65:
(7*7)+(6*3)+(5*8)+(4*3)+(3*8)+(2*6)+(1*5)=160
160 % 10 = 0
So 73838-65-0 is a valid CAS Registry Number.

(Thio)urea organocatalyst equilibrium acidities in DMSO
Jakab, Gergely,Tancon, Carlo,Zhang, Zhiguo,Lippert, Katharina M.,Schreiner, Peter R.
, p. 1724 - 1727 (2012)
Bordwell's method of overlapping indicators was used to determine the pKa values of some of the most popular (thio)urea organocatalysts via UV spectrophotometric titrations. The incremental effect of CF3 groups on acidic strength was
