Check Digit Verification of cas no

The CAS Registry Mumber 117872-49-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,8,7 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 117872-49:
(8*1)+(7*1)+(6*7)+(5*8)+(4*7)+(3*2)+(2*4)+(1*9)=148
148 % 10 = 8
So 117872-49-8 is a valid CAS Registry Number.

Solvent-free, efficient synthesis of 2,5-piperazinediones from Boc-protected dipeptide esters under microwave irradiation

López-Cobe?as, Alberto,Cledera, Pilar,Sánchez, J. Domingo,Pérez-Contreras, Rafael,López-Alvarado, Pilar,Ramos, M. Teresa,Avenda?o, Carmen,Menéndez, J. Carlos

, p. 1158 - 1160 (2005)

Microwave irradiation allows the efficient, solvent-free transformation of N-Boc dipeptide esters into 2,5-piperazinediones. The microwave-assisted conditions were found to be much better than traditional heating in terms of reaction time, yield and stere

Synthetic Studies on Bicyclomycin and its Analogues. Part 1. Synthesis of Substituted 2-Oxa-8,10-diazabicyclodecanes

Dawson, Ian M.,Gregory, Julian A.,Herbert, Richard B.,Sammes, Peter G.

, p. 2585 - 2594 (2007/10/02)

Methods have been developed for formation of the eight-membered oxygen-containing ring system (2) present in the antibiotic bicyclomycin.The procedure starts with N,N'-disubstituted piperazine-2,5-diones or the corresponding mono imino ethers.A new method is based on the oxidation of the mono imino ethers using 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) as oxidant: the bis imino ethers gave pyrazines under these conditions, whilst the parent piperazinedione proved to be unreactive.
