13312-85-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13312-85-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,3,1 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13312-85:
(7*1)+(6*3)+(5*3)+(4*1)+(3*2)+(2*8)+(1*5)=71
71 % 10 = 1
So 13312-85-1 is a valid CAS Registry Number.

Cyanative alkene-aldehyde coupling: Ni(0)-NHC-Et2AlCN mediated chromanol synthesis with high cis-selectivity at room temperature

Ho, Chun-Yu

supporting information; experimental part, p. 466 - 468 (2010/05/01)

Described are several classes of Ni(0) mediated cyanative alkene-aldehyde coupling reactions, providing 6-membered cores, which complement existing cyclization technology in several respects. Et2AlCN was used as both a cyclization accelerator and CN source. The NHC ligand may have a positive effect in differentiating reductive elimination and syn-β-hydride elimination.

Synthesis and antimicrobial activity of some heterocyclic compounds

Trivedi, P. B.,Undavia, N. K.,Dave, A. M.,Bhatt, K. N.,Desai, N. C.

, p. 497 - 500 (2007/10/02)

Condensation of 2-phenyl-3-(4-benzoyl hydride)-1,3-quinazolin-4(4H)-one (1) with various aldehydes gives 2-phenyl-3-(4-arylidene-benzoylhydrazide)-1,3-quinazolin-4(4H)-one (II), which on cycloaddition with mercaptoacetic acid yield 4-thiazolidinones (IIIa-o).Compound (I) on treatment with aromatic cyanohydrines and aryl isothiocyanates gives α-carbohydrazino nitriles of (IVa-m) and thiosemicarbazides (Va-l) respectively.The structures of III-V have been elucidated on the basis of their elemental analysis and spectral data.These compounds exhibit moderate to goodantibacterial and tuberculostatic activities.
