Check Digit Verification of cas no

The CAS Registry Mumber 1092493-80-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,2,4,9 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1092493-80:
(9*1)+(8*0)+(7*9)+(6*2)+(5*4)+(4*9)+(3*3)+(2*8)+(1*0)=165
165 % 10 = 5
So 1092493-80-5 is a valid CAS Registry Number.

Novel practical deprotection of N-Boc compounds using fluorinated alcohols

Choy, Jason,Jaime-Figueroa, Saul,Jiang, Laurence,Wagner, Paul

, p. 3840 - 3853 (2008)

The thermolytic deprotection of N-Boc compounds was accomplished using TFE (2,2,2-trifluoroethanol) or HFIP (hexafluoroisopropanol) as solvents. Even though the cleavage of the t-butylcarbamate (Boc) group can be achieved at solvent reflux temperature, the deprotection process was significantly accelerated under microwave-assisted conditions. The practicality of this methodology was demonstrated on alkyl, aryl, and heteroaromatic N-Boc-amines. Copyright Taylor & Francis Group, LLC.

Deprotection of N-BOC compounds

Page/Page column 5-6, (2009/07/10)

Organic compounds having nitrogen atoms protected with t-butoxycarbonyl are effectively deprotected by heating in a fluorinated alcohol solution.
