Check Digit Verification of cas no

The CAS Registry Mumber 845791-29-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,5,7,9 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 845791-29:
(8*8)+(7*4)+(6*5)+(5*7)+(4*9)+(3*1)+(2*2)+(1*9)=209
209 % 10 = 9
So 845791-29-9 is a valid CAS Registry Number.

A highly efficient CuI nanoparticles-catalyzed synthesis of tetrahydrochromenediones and dihydropyrano[c]chromenediones under grinding

Abdolmohammadi, Shahrzad,Ghiasi, Reza,Ahmadzadeh-Vatani, Sam

, p. 777 - 782 (2016/07/27)

A concise and CuI nanoparticle-catalyzed synthesis of tetrahydrochromenediones and dihydropyrano[c]chromenediones under solvent-free grinding conditions via the three-component condensation reaction of Meldrum's acid, an aromatic aldehyde, and an active m

Enantioselective synthesis of enol lactones from tandem Michael addition/lactonization catalyzed by a chiral squaramide catalyst

Zhao, Bo-Liang,Du, Da-Ming

, p. 310 - 317 (2014/04/03)

The enantioselective tandem Michael addition reaction of dimedone and related 1,3-dicarbonyl compounds with α,β-unsaturated N-acylated succinimides catalyzed by a chiral squaramide catalyst has been investigated. This reaction provides a new approach for the synthesis of chiral enol lactones in good yields with moderate to high enantioselectivities (up to 88% ee) through the enantioselective Michael addition followed by lactonization and removal of the succinimide auxiliary.
