882182-91-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 882182-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,2,1,8 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 882182-91:
(8*8)+(7*8)+(6*2)+(5*1)+(4*8)+(3*2)+(2*9)+(1*1)=194
194 % 10 = 4
So 882182-91-4 is a valid CAS Registry Number.

Difluorocarbene chemistry: Synthesis of gem-difluorocyclopropenyl ketones and gem-difluorinated dihydrofurans
Cheng, Zhan-Ling,Chen, Qing-Yun
, p. 478 - 480 (2007/10/03)
The cycloaddition reactions of difluorocarbene, generated by the decomposition of FSO2CF2CO2SiMe3, with α,β-acetylenic ketones give gem-difluorocyclopropenyl ketones in good yields. Treatment of these gem-difluo
