669692-33-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 669692-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,9,6,9 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 669692-33:
(8*6)+(7*6)+(6*9)+(5*6)+(4*9)+(3*2)+(2*3)+(1*3)=225
225 % 10 = 5
So 669692-33-5 is a valid CAS Registry Number.

Snowflake-Like Dendrimers via Site-Selective Synthesis of Dendrons
Kozaki, Masatoshi,Okada, Keiji
, p. 485 - 488 (2007/10/03)
(Equation presented) Snowflake-shaped dendrimers were prepared via site-selective synthesis of dendrons, where an attachment of encapsulating dendritic branches and an extension of phenylacetylenic units were alternatively manipulated on the structure of
