74948-31-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74948-31-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,4 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74948-31:
(7*7)+(6*4)+(5*9)+(4*4)+(3*8)+(2*3)+(1*1)=165
165 % 10 = 5
So 74948-31-5 is a valid CAS Registry Number.

Structure of Silylated Sulfonamides; a Silicon-29 Nuclear Magnetic Resonance Investigation

Iley, Jim,Bassindale, Alan R.,Patel, Pravin

, p. 77 - 80 (2007/10/02)

The structures of eighteen silylsulfonamides have been determined by 29Si n.m.r.The chemical shifts of the compounds were compared with those of model compounds.The N-silyl tautomer was the only isomer observed, except in cases where strongly electron-withdrawing groups (e.g.Cl, NMe2) were attached to nitrogen; in such cases the O-silyl tautomer dominates.The results have been rationalised in terms of the effect of substituents on the S-N ?-bond order.An estimate of the hitherto unmeasured S=N molar bond enthalpy as 325 kJ mol-1 was obtained.
