The CAS Registry Mumber 149219-06-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,2,1 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 149219-06:
(8*1)+(7*4)+(6*9)+(5*2)+(4*1)+(3*9)+(2*0)+(1*6)=137
137 % 10 = 7
So 149219-06-7 is a valid CAS Registry Number.

SYNTHESIS OF N-(SILATRANYLMETHYL)-SUBSTITUTED LACTAMS AND CARBOXYLIC ACID AMIDES

Kramarova, V.P.,Shipov, A.G.,Baukov, Yu.I.

, p. 2113 - 2119 (2007/10/02)

The general approach proposed for the synthesis of N-silatranylmethyl derivatives of lactams and carboxylic acid amides is based on the silyl variant of the akylation reaction.The treatment of N-trimethylsilyl-substituted lactams and carboxylic acid amides yielded N-trialkoxysilylmethyl lactam and amide derivatives.These were converted into the corresponding silatranes by the usual procedure (treating with triethanolamine in the presence of KOH).
