1263304-78-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1263304-78-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,3,0 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1263304-78:
(9*1)+(8*2)+(7*6)+(6*3)+(5*3)+(4*0)+(3*4)+(2*7)+(1*8)=134
134 % 10 = 4
So 1263304-78-4 is a valid CAS Registry Number.

Nucleophilic trifluoromethylation with organoboron reagents
Levin, Vitalij V.,Dilman, Alexander D.,Belyakov, Pavel A.,Struchkova, Marina I.,Tartakovsky, Vladimir A.
, p. 281 - 284 (2011)
Potassium trialkoxy(trifluoromethyl)borates are shown to behave as convenient reagents for nucleophilic trifluoromethylation of non-enolizable aldehydes and N-tosylimines to give CF3-substituted alcohols and N-tosylamines in good yields.
