Check Digit Verification of cas no

The CAS Registry Mumber 1283595-19-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,3,5,9 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1283595-19:
(9*1)+(8*2)+(7*8)+(6*3)+(5*5)+(4*9)+(3*5)+(2*1)+(1*9)=186
186 % 10 = 6
So 1283595-19-6 is a valid CAS Registry Number.

Cleavage of carbon-carbon bonds through the mild release of trifluoroacetate: Generation of α,α-difluoroenolates for aldol reactions

Han, Changho,Kim, Eun Hoo,Colby, David A.

, p. 5802 - 5805 (2011/05/19)

The selective cleavage of carbon-carbon bonds is a significant challenge in synthetic chemistry, yet this strategy can be a powerful way to generate reactive intermediates. We have discovered that, through the facile release of trifluoroacetate which occurs by C-C bond scission, difluoroenolates can be generated under very mild reaction conditions. Unlike existing reactions, this method is not limited to a small group of fluorinated building blocks. We have applied this process to the aldol reaction to install difluoromethylene groups.
