Check Digit Verification of cas no

The CAS Registry Mumber 292163-77-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,2,1,6 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 292163-77:
(8*2)+(7*9)+(6*2)+(5*1)+(4*6)+(3*3)+(2*7)+(1*7)=150
150 % 10 = 0
So 292163-77-0 is a valid CAS Registry Number.

Palladium-catalyzed O-allylation of α-hydroxy carbonyl compounds

Schmidt, Bernd,Nave, Stefan

, p. 531 - 537 (2007/10/03)

α-Hydroxy carbonyl compounds undergo smooth O-allylation using allylic carbonates and Pd(0) catalysts. This method has significant advantages over other O-allylation methods as it provides a solution to several problems previously observed for this synthe

Diastereoselective Ring-Closing Metathesis in the Synthesis of Dihydropyrans

Schmidt, Bernd,Wildemann, Holger

, p. 5817 - 5822 (2007/10/03)

An investigation into the factors influencing the diastereochemical outcome of the ring-closing metathesis based synthesis of dihydropyrans is presented in this paper. Divinyl carbinols derived from α-hydroxy carboxylic acid esters are elaborated to trienes with two diastereotopic vinyl moieties. Depending on the steric demand of the oxo substituent of the divinyl carbinol moiety (either unprotected OH, TBDMS, or benzyl ether) different diastereomers are preferrably formed upon ring-closing metathesis. An extension to diastereoselective double ring-closing metathesis in the formation of spirocycles has also been investigated.
