Check Digit Verification of cas no

The CAS Registry Mumber 74688-68-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,8 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74688-68:
(7*7)+(6*4)+(5*6)+(4*8)+(3*8)+(2*6)+(1*8)=179
179 % 10 = 9
So 74688-68-9 is a valid CAS Registry Number.

Catalytic Allylation of Aldehydes Using Unactivated Alkenes

Tanabe, Shun,Mitsunuma, Harunobu,Kanai, Motomu

supporting information, p. 12374 - 12381 (2020/07/14)

Simple feedstock organic molecules, especially alkenes, are attractive starting materials in organic synthesis because of their wide availability. Direct utilization of such bulk, inert organic molecules for practical and selective chemical reactions, however, remains limited. Herein, we developed a ternary hybrid catalyst system comprising a photoredox catalyst, a hydrogen-atom-transfer catalyst, and a chromium complex catalyst, enabling catalytic allylation of aldehydes with simple alkenes, including feedstock lower alkenes. The reaction proceeded under visible-light irradiation at room temperature and with high functional group tolerance. The reaction was extended to an asymmetric variant by employing a chiral chromium complex catalyst.

A convenient one pot allylation of aldehydes with allylic halides prepared in situ from allylic alcohols in the presence of metallic bismuth

Wada,Miyoshi,Nishio,Murakami,Fukuma

, p. 689 - 692 (2007/10/03)

The allylation of carbonyl compounds is one of the most fundamental C-C bond forming reactions in organic synthesis. Numerous efficient techniques using allylic organometallics derived from a number of metallic elements have been reported, e.g., the Grign
