3784-12-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3784-12-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,8 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3784-12:
(6*3)+(5*7)+(4*8)+(3*4)+(2*1)+(1*2)=101
101 % 10 = 1
So 3784-12-1 is a valid CAS Registry Number.

Diphilic carbosilane dendrimers with different densities of the hydrophilic layer

Getmanova,Tereshchenko,Ignat'eva,Tatarinova,Myakushev,Muzafarov

, p. 137 - 143 (2007/10/03)

A universal method for the synthesis of hydrophilic dendrimers was considered. The method is based on a combination of carbosilane dendrimers with different molecular organizations and hydrophilizing agents, viz., substituted hydride silanes containing one and three protected hydroxyl groups. The combination of a limited set of the mentioned reagents makes it possible to control the ratio of hydrophilic and hydrophobic moieties of the molecular structure in wide limits. A simple and convenient method for the removal of trimethylsilyl protection of hydroxyl groups in the surface layer of dendrimers was developed.
