129758-74-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129758-74-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,7,5 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129758-74:
(8*1)+(7*2)+(6*9)+(5*7)+(4*5)+(3*8)+(2*7)+(1*4)=173
173 % 10 = 3
So 129758-74-3 is a valid CAS Registry Number.

CALIXARENES WITH RESORCINOL UNITS INCORPORATED IN 2,6-POSITION
Tabatabai, Monir,Vogt, Walter,Boehmer, Volker
, p. 3295 - 3298 (2007/10/02)
Calixarenes containing one or two resorcinol units incorporated via their 2,6-positions were prepared by fragment condensation.Due to the cyclic array of intramolecular hydrogen bonds these molecules assume the cone-conformation.
