238093-19-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 238093-19-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,8,0,9 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 238093-19:
(8*2)+(7*3)+(6*8)+(5*0)+(4*9)+(3*3)+(2*1)+(1*9)=141
141 % 10 = 1
So 238093-19-1 is a valid CAS Registry Number.

Preparation of a new class of cleavable surfactants based on the silicon-carbon bond
Noronha, Glenn,Nguyen, Khanhlinh T.
, p. 4935 - 4938 (1999)
The ability of silicon to direct electrophiles to the ipso-position is used in developing a new class of cleavable amphiphiles containing an acid labile silicon-carbon (aromatic) bond. The synthesis of these amphiphiles is carried out in four steps to yie
