The CAS Registry Mumber 213964-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,9,6 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 213964-13:
(8*2)+(7*1)+(6*3)+(5*9)+(4*6)+(3*4)+(2*1)+(1*3)=127
127 % 10 = 7
So 213964-13-7 is a valid CAS Registry Number.

ortho-halogeno substituents effect in asymmetric cyclization of 4-aryl-4-pentenals using a rhodium catalyst

Fujio, Masakazu,Tanaka, Masakazu,Wu, Xiao-Ming,Funakoshi, Kazuhisa,Sakai, Kiyoshi,Suemune, Hiroshi

, p. 881 - 882 (2007/10/03)

Asymmetric cyclization of 4-aryl-4-pentenals by using a cationic [Rh((R)-BINAP)]ClO4 afforded (3R)-3-substituted cyclopentanones; on the other hand, the cyclization of 4-pentenals bearing ortho-halogeno phenyl groups afforded the opposite (3S)-ones.
