197783-86-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197783-86-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,7,8 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 197783-86:
(8*1)+(7*9)+(6*7)+(5*7)+(4*8)+(3*3)+(2*8)+(1*6)=211
211 % 10 = 1
So 197783-86-1 is a valid CAS Registry Number.

CF2H, a Hydrogen Bond Donor
Sessler, Chanan D.,Rahm, Martin,Becker, Sabine,Goldberg, Jacob M.,Wang, Fang,Lippard, Stephen J.
, p. 9325 - 9332 (2017)
The CF2H group, a potential surrogate for the OH group, can act as an unusual hydrogen bond donor, as confirmed by crystallographic, spectroscopic, and computational methods. Here, we demonstrate the bioisosterism of the OH and CF2H
