Check Digit Verification of cas no

The CAS Registry Mumber 299433-96-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,9,4,3 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 299433-96:
(8*2)+(7*9)+(6*9)+(5*4)+(4*3)+(3*3)+(2*9)+(1*6)=198
198 % 10 = 8
So 299433-96-8 is a valid CAS Registry Number.

Synthesis of New Diols Derived from Dianhydrohexitols Ethers under Microwave-Assisted Phase Transfer Catalysis

Chatti, Saber,Bortolussi, Michel,Loupy, André

, p. 5877 - 5883 (2007/10/03)

Alkylation of mono-benzylated isosorbide and isomannide was performed under microwave assisted phase transfer catalysis (PTC). A small amount of solvent was necessary to provide good yields (90-96%) within 15 min. In order to minimize the competitive elimination, halide leaving group was changed to tosylate as competitive S(N)2-E2 processes were involved. After removal of benzyl moiety by hydrogenation, a series of new diols from dianhydrohexitols were thus prepared. (C) 2000 Elsevier Science Ltd.
