126568-41-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126568-41-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,5,6 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 126568-41:
(8*1)+(7*2)+(6*6)+(5*5)+(4*6)+(3*8)+(2*4)+(1*1)=140
140 % 10 = 0
So 126568-41-0 is a valid CAS Registry Number.

ENANTIOSELECTIVE TOTAL SYNTHESIS OF (+)-(S)-DIHYDROPERIPHYLLINE
Kaseda, Takehiko,Kikuchi, Toyohiko,Kibayashi, Chihiro
, p. 4539 - 4542 (2007/10/02)
The first enantioselective total synthesis of (+)-(S)-dihydroperiphylline was achieved from (S)-β-phenyl-β-alanine, prepared by chelation controlled phenylation of the Schiff base, by a new route involving 13-membered lactam formation via iminium cyclization.
