156340-45-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156340-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,3,4 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 156340-45:
(8*1)+(7*5)+(6*6)+(5*3)+(4*4)+(3*0)+(2*4)+(1*5)=123
123 % 10 = 3
So 156340-45-3 is a valid CAS Registry Number.

An Unusual C-4a Hydroxylated Decahydroquinolone
Joseph, Sajan P.,Comins, Daniel L.,Singh, Phirtu
, p. 950 - 952 (1994)
The crystal structure and the relative stereochemistry of the four asymmetric centers of an unusual C-4a hydroxylated decahydroquinolone, phenyl 1,2α,3,4,4aα,5β,6,7,8,8aα-decahydro-4a-hydroxy-4-oxo-2-propyl-5-vinylquinoline-1-carboxylate, C21H27NO4, are reported.The H and OH groups at the ring juncture are cis to each other as are the two H atoms α to the N atom.The vinyl and OH groups are also cis to each other.The N atom is sp2 hybridized.
