885223-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 885223-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,5,2,2 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 885223-99:
(8*8)+(7*8)+(6*5)+(5*2)+(4*2)+(3*3)+(2*9)+(1*9)=204
204 % 10 = 4
So 885223-99-4 is a valid CAS Registry Number.

S,O-acetals as novel "chiral aldehyde" equivalents
Trost, Barry M.,Crawley, Matthew L.,Lee, Chul Bom
, p. 2171 - 2187 (2008/01/27)
Palladium-catalyzed asymmetric allylic alkylations (AAA) to form "chiral aldehyde" equivalents were investigated. α-Acetoxysulfones were formed in high enantiomeric excess as single regioisomers in AAA reactions of allylic geminal dicarboxylates with sodi
