105283-33-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105283-33-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,2,8 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 105283-33:
(8*1)+(7*0)+(6*5)+(5*2)+(4*8)+(3*3)+(2*3)+(1*3)=98
98 % 10 = 8
So 105283-33-8 is a valid CAS Registry Number.

Synthesis of N-Substituted Prodigiosenes
Brown, David,Griffiths, David,Rider, Margaret E.,Smith, Rodney C.
, p. 455 - 464 (2007/10/02)
Prodigiosenes bearing N-methyl or N-benzyl groups in each of the three pyrrole rings have been prepared by coupling either a bipyrrole with a pyrrolecarbaldehyde or a bipyrrolecarbaldehyde with an α-free pyrrole.Synthesis via the bipyrrole route can lead
