The CAS Registry Mumber 17993-88-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,9 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 17993-88:
(7*1)+(6*7)+(5*9)+(4*9)+(3*3)+(2*8)+(1*8)=163
163 % 10 = 3
So 17993-88-3 is a valid CAS Registry Number.

Tetrabutylammonium phthalimide-N-oxyl: An efficient organocatalyst for trimethylsilylation of alcohols and phenols with hexamethyldisilazane

Dekamin,Yazdaninia,Mokhtari,Naimi-Jamal

experimental part, p. 537 - 544 (2012/06/18)

Tetrabutylammonium phthalimide-N-oxyl (TBAPINO) was found to be an effective organocatalyst for rapid, simple and chemoselective protection of the hydroxyl group of alcohols and phenols using hexamethyldisilazane (HMDS) under mild conditions. The low catalyst loading, high to quantitative yields and simple removal of the catalyst from the reaction mixture illustrate the other attractive features of this protocol.
