195051-50-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 195051-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,0,5 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 195051-50:
(8*1)+(7*9)+(6*5)+(5*0)+(4*5)+(3*1)+(2*5)+(1*0)=134
134 % 10 = 4
So 195051-50-4 is a valid CAS Registry Number.

N-(tert -butoxycarbonyl)- N -[(triethylenediammonium)sulfonyl]azanide: A convenient sulfamoylation reagent for alcohols

Armitage, Ian,Berne, Alexander M.,Elliott, Eric L.,Fu, Mingkun,Hicks, Frederick,McCubbin, Quentin,Zhu, Lei

supporting information; experimental part, p. 2626 - 2629 (2012/07/28)

A convenient and efficient procedure is described for the sulfamoylation of alcohols using N-(tert-butoxycarbonyl)-N-[(triethylenediammonium)sulfonyl] azanide (1). The ambient temperature stable reagent 1 reacts with phenols as well as primary and secondary alcohols to give high to modest yields. The relative reaction rate of substrates was determined (primary > phenol > secondary ? tertiary). The reagent's utility as a selective sulfamoylation reagent with polyols is also demonstrated.
