Check Digit Verification of cas no

The CAS Registry Mumber 164226-14-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,2,2 and 6 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 164226-14:
(8*1)+(7*6)+(6*4)+(5*2)+(4*2)+(3*6)+(2*1)+(1*4)=116
116 % 10 = 6
So 164226-14-6 is a valid CAS Registry Number.

Sustainable and chemoselective N-Boc protection of amines in biodegradable deep eutectic solvent

Azizi, Najmedin,Shirdel, Fatemeh

, p. 1069 - 1074 (2017)

Abstract: A green and practical approach for the chemoselective N-tert-butyloxycarbonylation of structurally diverse amines with di-tert-butyl dicarbonate (Boc2O) is described. Selective N-Boc protection was achieved in excellent yields in urea-choline chloride deep eutectic solvent (DES) as the most promising environmentally benign and cost-effective solvent under mild reaction condition. DES can protect various aromatic and aliphatic amines using Boc2O in good to excellent yields in short reaction times without any side products.
