Check Digit Verification of cas no

The CAS Registry Mumber 4895-47-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,9 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4895-47:
(6*4)+(5*8)+(4*9)+(3*5)+(2*4)+(1*7)=130
130 % 10 = 0
So 4895-47-0 is a valid CAS Registry Number.

Efficient Difluoromethylation of Alcohols Using TMSCF2Br as a Unique and Practical Difluorocarbene Reagent under Mild Conditions

Xie, Qiqiang,Ni, Chuanfa,Zhang, Rongyi,Li, Lingchun,Rong, Jian,Hu, Jinbo

supporting information, p. 3206 - 3210 (2017/03/17)

A general method for the efficient difluoromethylation of alcohols using commercially available TMSCF2Br (TMS=trimethylsilyl) as a unique and practical difluorocarbene source is developed. This method allows primary, secondary, and even tertiary alkyl difluoromethyl ethers to be synthesized under weakly basic or acidic conditions. The reaction mainly proceeds through the direct interaction between a neutral alcohol and difluorocarbene, which is different from the difluoromethylation of phenols. Moreover, alcohols containing other moieties that are also reactive toward difluorocarbene can be transformed divergently by using TMSCF2Br. This research not only solves the synthetic problem of difluorocarbene-mediated difluoromethylation of alcohols, it also provides new insights into the different reaction mechanisms of alcohol difluoromethylation and phenol difluoromethylation with difluorocarbene species.

Aryloxy Radicals from Diaryloxydiazirines: α-Cleavage of Diaryloxycarbenes or Excited Diazirines?

Fede, Jean-Marie,Jockusch, Steffen,Lin, Nan,Moss, Robert A.,Turro, Nicholas J.

, p. 5027 - 5030 (2007/10/03)

(Equation presented) The synthesis of diaryloxydiazirines, precursors to diaryloxycarbenes, is described. Thermolyses of the diazirines afford anticipated carbene products, but photolyses afford both carbenes and aryloxy radicals by α-scission. UV spectra of the carbenes and radicals are observed.
