283179-33-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 283179-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,3,1,7 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 283179-33:
(8*2)+(7*8)+(6*3)+(5*1)+(4*7)+(3*9)+(2*3)+(1*3)=159
159 % 10 = 9
So 283179-33-9 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
