74170-42-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74170-42-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,7 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74170-42:
(7*7)+(6*4)+(5*1)+(4*7)+(3*0)+(2*4)+(1*2)=116
116 % 10 = 6
So 74170-42-6 is a valid CAS Registry Number.

SYNTHESIS OF dl-SEPTICINE
Iwashita, Takashi,Suzuki, Masahiro,Kusumi, Takenori,Kakisawa, Hiroshi
, p. 383 - 386 (2007/10/02)
Cyloaddition reaction of 1-pyrroline 1-oxide with 2,3-bis(3,4-dimethoxyphenyl)butadiene proceeded regioselectively to give two stereoisomeric isoxazolidine derivatives, one of which was converted into septicine by three-step reactions.
