823785-38-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 823785-38-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,3,7,8 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 823785-38:
(8*8)+(7*2)+(6*3)+(5*7)+(4*8)+(3*5)+(2*3)+(1*8)=192
192 % 10 = 2
So 823785-38-2 is a valid CAS Registry Number.

Rhodium-catalyzed intramolecular hydroacylation of 5- and 6-alkynals: Convenient synthesis of α-alkylidenecycloalkanones and cycloalkenones

Takeishi, Kenzo,Sugishima, Koudai,Sasaki, Kaori,Tanaka, Ken

, p. 5681 - 5688 (2007/10/03)

A novel intramolecular hydroacylation of 5- and 6-alkynals leading to α-alkylidenecycloalkanones was accomplished by using cationic a rhodium(I)/BINAP complex. For all cyclizations described, a single (E)-olefin isomer was obtained. At elevated temperature, hydroacylation and double bond migration of 5- and 6-alkynals proceeded in a one-pot reaction to give cycloalkenones. An intramolecular hydroacylation of a 7-alkynal was unsuccessful. This method represents an attractive new route to highly functionalized α-alkylidenecycloalkanones and cycloalkenones.
