Check Digit Verification of cas no

The CAS Registry Mumber 218623-12-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,6,2 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 218623-12:
(8*2)+(7*1)+(6*8)+(5*6)+(4*2)+(3*3)+(2*1)+(1*2)=122
122 % 10 = 2
So 218623-12-2 is a valid CAS Registry Number.

Solvent free tetrahydropyranylation of alcohols and phenols over sulfuric acid adsorbed on silica gel

Heravi, Majid M.,Ajami, Dariush,Ghassemzadeh, Mitra

, p. 1013 - 1016 (1999)

Alcohols and phenols are tetrahydropyranylated in the presence of sulfuric acid adsorbed on silica gel in high to excellent yields in solvent free conditions and is expedited by microwave irradiation. Addition of methanol performs the complete deprotection.

Efficient method for tetrahydropyranylation of alcohols and phenols and deprotection of THP ethers using H14[NaP5W 30O110] as a Green Catalyst

Heravi, Majid M.,Haghighi, Masoumeh,Derikvand, Fatemeh,Bamoharram, Fatemeh F.

, p. 3103 - 3107 (2007/10/03)

A simple and effective method for tetrahydropyranylation of alcohols and phenols and the regeneration of THP ethers using a catalytic amount of H 14[NaP5W30O110] is reported. Copyright Taylor & Francis Group, LLC.
