56164-42-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56164-42-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,1,6 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 56164-42:
(7*5)+(6*6)+(5*1)+(4*6)+(3*4)+(2*4)+(1*2)=122
122 % 10 = 2
So 56164-42-2 is a valid CAS Registry Number.

Synthesis of 3-chloro-2-formylpyrrole derivatives
Robertson, Jeremy,Kuhnert, Nikolai,Zhao, Yuekun
, p. 2415 - 2420 (2007/10/03)
Regioselective deprotonation of 3-chloro-1-tosylpyrrole is used to prepare the 2-formyl derivative. Application of this chemistry in a synthesis of the left hand pyrrolo-furan substructure of roseophilin is described.
