Check Digit Verification of cas no

The CAS Registry Mumber 634164-29-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,4,1,6 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 634164-29:
(8*6)+(7*3)+(6*4)+(5*1)+(4*6)+(3*4)+(2*2)+(1*9)=147
147 % 10 = 7
So 634164-29-7 is a valid CAS Registry Number.

Hydropyridylation of Olefins by Intramolecular Minisci Reaction

Bordi, Samuele,Starr, Jeremy T.

, p. 2290 - 2293 (2017/05/12)

An unprecedented cheap, mild and easy methodology for an intramolecular Minisci reaction based on a hydrogen atom transfer (HAT) initiated hydrofunctionalization of olefins was developed. The method is suitable for the construction of unusual dihydropyrano-pyridine and 1,2,3,4-tetrahydronaphthiridine structures and, unlike most similar reactions, does not require exclusion of air from the reaction medium.

Diastereoselective intramolecular SmI2-H2O-amine mediated couplings

Dahlen, Anders,Petersson, Annika,Hilmersson, Goeran

, p. 2423 - 2426 (2007/10/03)

The effectiveness of SmI2-H2O-amine mixture for intramolecular couplings was discussed. Diastereoselectivities in the coupling of O-cyclohexanyliodophenol derivatives were provided into heterocycles. The amount of coupled product improved significantly as SmI2, the substrate and amine were premixed followed by a gradual addition of water.
