1338328-42-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1338328-42-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,3,2 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1338328-42:
(9*1)+(8*3)+(7*3)+(6*8)+(5*3)+(4*2)+(3*8)+(2*4)+(1*2)=159
159 % 10 = 9
So 1338328-42-9 is a valid CAS Registry Number.

Synthesis of α-halo-α,α-difluoromethyl ketones by a trifluoroacetate release/halogenation protocol
John, Jinu P.,Colby, David A.
, p. 9163 - 9168 (2011/12/16)
Three series of α-halo-α,α-difluoromethyl ketones are prepared from highly α-fluorinated gem-diols by exploiting the facile release of trifluoroacetate, followed by immediate trapping of the liberated α,α-difluoroenolate with an electrophilic chlorine, br
