Check Digit Verification of cas no

The CAS Registry Mumber 83318-92-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,3,1 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 83318-92:
(7*8)+(6*3)+(5*3)+(4*1)+(3*8)+(2*9)+(1*2)=137
137 % 10 = 7
So 83318-92-7 is a valid CAS Registry Number.

Ikeshita, Kei-Ichiro,Kihara, Nobuhiro,Ogawa, Akiya

, p. 8773 - 8775 (2005)

The reaction of dithioacetals with gallium(II) chloride followed by the acid treatment afforded sulfides in good yields.

URACIL NUCLEOTIDE ANALOGUES, THEIR PREPARATION METHOD AND USE THEREOF

-

Page/Page column 64; 65, (2016/10/08)

The invention relates to uracil nucleotide analogues, their preparation method and use thereof. Specifically, the invention provides the uracil nucleotide analogues with the formula (I), their stereoisomers and pharmaceutical acceptable salts, the preparation method and use. These compounds are RNA-dependent RNA viral replication inhibitors, and can be used as HCV NS5B polymerase inhibitors, HCV replication inhibitors as well as for the treatment of hepatitis C infection in mammals. They have broad application prospects and are expected to develop a new generation of antiviral drugs.

Lewis Acid-Catalyzed Deprotection of p-Methoxybenzyl Ether

Bouzide, Abderrahim,Sauvé, Gilles

, p. 1153 - 1154 (2007/10/03)

The p-methoxybenzyl protecting group was readily removed from alcohols and phenols using catalytic amounts of AlCl3 or SnCl2 · 2H2O in the presence of EtSH at room temperature. Under these mild conditions other protecting groups such as methyl and benzyl ethers, p-nitrobenzoyl esters, TBDPS ethers and isopropylidene acetal were unchanged.
