Check Digit Verification of cas no
The CAS Registry Mumber 634-55-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 634-55:
(5*6)+(4*3)+(3*4)+(2*5)+(1*5)=69
69 % 10 = 9
So 634-55-9 is a valid CAS Registry Number.

Flash preparation of carbenoids: A different performance of cyanogen bromide
Hedayati, Mohammad Jalilzadeh,Pesyan, Nader Noroozi
, p. 2081 - 2089 (2015/04/22)
Cyanogen halides are known substances for the cyanating reaction. There are a few evidences for bromination reaction too. On the other hand carbenes are known as very important substances due to their remarkable reactions. Unfortunately carbenes at room temperature are very unstable and there is not a simple method for preparation of them. In most cases the isolation is not possible. We have reported a new reliable and fast preparation method of almost stable carbenoids. The mechanism of the formation has been discussed.
Synthesis and cyclization reaction of pyrazolin-5-one derivatives
Jung, Jae-Chul,Blake Watkins,Avery, Mitchell A.
, p. 77 - 94 (2007/10/03)
A versatile synthetic method for preparing 3-pyrazolin-5-ones and 5,8-dihydro-1H-pyrazolo[1,2-a]pyridazines from simple β-keto esters is demonstrated. The synthetic strategies involve the acylation of β-keto esters, cyclocondensation with hydrazine followed by trapping with a diene under oxidative conditions.
