145653-72-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145653-72-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,6,5 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 145653-72:
(8*1)+(7*4)+(6*5)+(5*6)+(4*5)+(3*3)+(2*7)+(1*2)=141
141 % 10 = 1
So 145653-72-1 is a valid CAS Registry Number.

Synthesis of enantiomerically pure 6,10-epoxybenzocycloocten-7-amines with CNS-activity
Wunsch,Zott,Hofner
, p. 733 - 739 (2007/10/02)
In an oxa-Pictet-Spengler reaction the methyl (S)-phenyllactate 6 and methyl levulinate (7a) are condensed to the 2-benzopyrans cis-8a and trans-8a, which react with CH3I to yield the dimethyl ethers cis-9a and trans-9a. Cis-9a and trans-9a can
