867193-31-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 867193-31-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,7,1,9 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 867193-31:
(8*8)+(7*6)+(6*7)+(5*1)+(4*9)+(3*3)+(2*3)+(1*1)=205
205 % 10 = 5
So 867193-31-5 is a valid CAS Registry Number.

Synthesis of dendrimers with terminal formyl groups
Loim,Kelbyscheva
, p. 2080 - 2085 (2007/10/03)
A method for preparation of dendrons and dendrimers with formyl groups at the terminal aromatic rings, ether bonds in the branching blocks, and ester bonds in the core of the macromolecules is proposed. A way for the selective synthesis of p-hydroxymethylbenzaldehyde is described.
