352555-25-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 352555-25-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,2,5,5 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 352555-25:
(8*3)+(7*5)+(6*2)+(5*5)+(4*5)+(3*5)+(2*2)+(1*5)=140
140 % 10 = 0
So 352555-25-0 is a valid CAS Registry Number.

Torp-Ziegler cyclization in the synthesis of 3-amino-4-cyanopyrrole derivatives
Ryndina,Kadushkin,Solov'eva,Granik
, p. 1409 - 1420 (2007/10/03)
Polyfunctional derivatives of 3-aminopyrrole have been synthesized from several substituted β-enamino nitriles using Torp-Ziegler cyclization. These compounds are starting materials for further conversions, particularly for the synthesis of pyrrolo[3,2-d]
