88257-87-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88257-87-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,2,5 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 88257-87:
(7*8)+(6*8)+(5*2)+(4*5)+(3*7)+(2*8)+(1*7)=178
178 % 10 = 8
So 88257-87-8 is a valid CAS Registry Number.

PREPARATION AND CARBONYL ADDITION OF γ,γ-DIFLUOROALLYLSILANES
Hiyama, Tamejiro,Obayashi, Michio,Sawahata, Miwa
, p. 4113 - 4116 (2007/10/02)
The reaction of 3,3,3-trifluoropropenes with disilane/tetrabutylammonium fluoride or silyllithium reagent gives γ,γ-difluoroallylsilanes which afford gem-difluoroallyl adducts of aldehydes and ketones with the aid of a catalyst such as potassium t-butoxid
