756820-13-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 756820-13-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,5,6,8,2 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 756820-13:
(8*7)+(7*5)+(6*6)+(5*8)+(4*2)+(3*0)+(2*1)+(1*3)=180
180 % 10 = 0
So 756820-13-0 is a valid CAS Registry Number.

Intramolecular [4+2] cycloaddition reactions of indolylalkylpyridazines: Synthesis of annulated carbazoles
Haider, Norbert,K?ferb?ck, Johann
, p. 6495 - 6507 (2004)
Mono- and bicyclic 1,2-diazines tethered to indole dienophiles by alkylene chains were found to undergo thermally induced intramolecular Diels-Alder reactions with inverse electron demand, affording tetra- and pentacyclic condensed carbazoles.
