The CAS Registry Mumber 1186338-33-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,6,3,3 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1186338-33:
(9*1)+(8*1)+(7*8)+(6*6)+(5*3)+(4*3)+(3*8)+(2*3)+(1*3)=169
169 % 10 = 9
So 1186338-33-9 is a valid CAS Registry Number.

Reaction of difluorocarbene with propargyl esters and efficient synthesis of difluorocyclopropyl ketones

Hang, Xiao-Chun,Gu, Wei-Peng,Chen, Qing-Yun,Xiao, Ji-Chang

, p. 6320 - 6324 (2009)

Difluorocarbene generated from FSO2CF2CO2SiMe3 (TFDA) at 120 °C could reacted with terminal alkynes having an ester group at the α position to the triple bond. Difluorocyclopropenes were further converted to difluorocyclopropyl ketones under alkaline condition. Mechanism for the conversion was studied.
