Check Digit Verification of cas no

The CAS Registry Mumber 161511-14-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,5,1 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 161511-14:
(8*1)+(7*6)+(6*1)+(5*5)+(4*1)+(3*1)+(2*1)+(1*4)=94
94 % 10 = 4
So 161511-14-4 is a valid CAS Registry Number.

Novel Cyclobutane Carbocyclic Nucleosides

Mevellec, Laurence,Huet, Francois

, p. 13145 - 13154 (1994)

Epoxidation of cis-3,4-bis(benzyloxymethyl)cyclobut-1-ene 4 gave compounds 7a and 7b which were separated.Reaction of the cis-epoxide 7a with adenine led to the N-9 and N-7 attack products, 10a and 10b, respectively.In the same conditions, the trans-epoxi

Preparation Involving a C4-C3 Ring Contraction in the Key Step of a Novel Cyclopropane Carbocyclic Nucleoside

Mevellec, Laurence,Huet, Francois

, p. 7441 - 7444 (2007/10/02)

Cis-3,4-bis(benzyloxymethyl)cyclobut-1-ene 1 mainly led to bromohydrin 5 with a cis relationship between bromine and the benzyloxymethyl groups.The stereospecific ring contraction of 5 afforded aldehyde 7 which could be converted into the nucleoside analo
