Check Digit Verification of cas no

The CAS Registry Mumber 21841-30-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,4 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21841-30:
(7*2)+(6*1)+(5*8)+(4*4)+(3*1)+(2*3)+(1*0)=85
85 % 10 = 5
So 21841-30-5 is a valid CAS Registry Number.

Preparation and complete 1 H and 13C assignment of some pentacyclo[5.4.0.02,6.03,10.05,9]undecane- 8,11-dione (PCUD) derivatives

Kenwright, Alan M.,Sellars, Jonathan D.

, p. 803 - 808 (2013/01/15)

The preparation of a number of alkyl and alkoxy derivatives of pentacyclo[5.4.0.02,6.03,10.05,9]undecane-8,11- dione derivatives utilising a cheap, practical, low energy, 'green', single-pass continuous flow photochemical reactor is reported. Their 1 H and 13C NMR spectra are fully assigned, revealing some general characteristics not previously reported for this class of compound, which should aid the assignment and prediction of the NMR spectra of PCUD derivatives.

LEWIS ACID CATALYSED CYCLOREVERSION OF COOKSON'S CAGE KETONES UNDER AMBIENT CONDITIONS: MODEL SYSTEM FOR LIGHT ENERGY CONVERSION

Mehta, Goverdhan,Reddy, D. Sivakumar,Reddy, A. Veera

, p. 2275 - 2278 (2007/10/02)

Design of 'push-pull' Cookson's cage ketones and their quantitative cycloreversion to cis, syn, cis-triquinanes at room temp, under Lewis acid catalysis, is reported.This observation has promising ramifications on the utility of 12 system for reversible storage of solar energy.
