130655-36-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 130655-36-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,5 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 130655-36:
(8*1)+(7*3)+(6*0)+(5*6)+(4*5)+(3*5)+(2*3)+(1*6)=106
106 % 10 = 6
So 130655-36-6 is a valid CAS Registry Number.

A PRACTICAL ROUTE TO SPIRO-TYPE HETEROCYCLES RELATED TO ERYTHRINAN

Tsuda, Yoshisuke,Sakai, Yuki,Kaneko, Mari,Ishiguro, Yukie,Isobe, Kimiaki,et al.

, p. 431 - 436 (2007/10/02)

A new method synthesizing spiro-type heterocycles by intramolecular cyclization of 3,3-disubstituted dioxopyrrolines was presented.The method is particularly useful in synthesizing erythrinans and has the following advantages: 1) it is of short steps with high yield ( one-pot reaction is possible ), 2) an activating group at ring A is not necessary, and 3) the procedure can be carried out without protection of phenolic hydroxyl groups.Wide applicability of this method was also shown by synthesizing C-nor and C-homoerythrinans, and other variants which carry heterocycles at ring A instead of benzenoids.
