881744-38-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 881744-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,7,4 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 881744-38:
(8*8)+(7*8)+(6*1)+(5*7)+(4*4)+(3*4)+(2*3)+(1*8)=203
203 % 10 = 3
So 881744-38-3 is a valid CAS Registry Number.

From ketones, aldehydes or alkyl halides to terminal 1,1-difluoroolefins using BrF3
Hagooly, Aviv,Rozen, Shlomo
, p. 1239 - 1245 (2007/10/03)
Terminal difluoromethylenes were prepared by two different routes: (a) by treating ketones and aldehydes with bis(methylthio)methane, producing 2-alkyl-1,1-bis(methylthio)alkene (2) (b) reacting alkyl halides with tris(methylthio)methane forming 1-alkyl-1
