The chemical compound in question is a complex organic molecule with a highly specific structure. It is a hexahydro-indan derivative, which means it is a type of indane molecule that has undergone hydrogenation, reducing the number of double bonds. The compound is characterized by a 3aR-methyl-3c-(1R:4R)-1,4,5-trimethyl-hexen-2t-yl group, indicating the presence of a methyl group at the 3a position and a specific arrangement of methyl groups on a hexenyl moiety. Additionally, it features a 7-[2-((2S)-5t-hydroxy-2r-methyl-cyclohexyliden-(seqcis))-aethyliden-(seqtrans)] group, which describes a cyclohexane ring with a hydroxyl group and a methyl group in a specific configuration, connected to an ethylidene group in a trans configuration. The compound's structure is further defined by the presence of a 7atH, indicating a hydrogen atom at the 7a position in a half-chair conformation. This molecule represents a sophisticated example of organic chemistry, with its intricate arrangement of functional groups and stereochemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 807-27-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,0 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 807-27:
(5*8)+(4*0)+(3*7)+(2*2)+(1*7)=72
72 % 10 = 2
So 807-27-2 is a valid CAS Registry Number.

Hydrotitanation-Protonation of Vitamin D2 and Its Analogues: An Efficient Method for the Preparation of 10,19-Dihydrovitamins D2 Including Dihydrotachysterol2

Cota, J. G.,Meilan, M. C.,Mourino, A.,Castedo, L.

, p. 6094 - 6099 (2007/10/02)

In this study we describe an easy and efficient method for the preparation of the known 10,19-dihydrovitamins D2 2b (DHV2-II), 2c (DHV2-IV), 3c (dihydrotachysterol2, DHT2), and the new dihydrovitamins D2 2f and 2g.This method is based on the regioselective hydrometalation reaction of vitamin D2 and its derivatives with the system Cp2TiCl2-LiAlH4 or Cp2TiCl2-Red-Al (Aldrich).Under optimal conditions, the reaction with the former of these hydrometalating systems takes place with a high degree of stereoselectivity and allows labelling at C-19.
