Check Digit Verification of cas no

The CAS Registry Mumber 129758-77-6 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 7 respectively.
Calculate Digit Verification of CAS Registry Number 129758-77:
(8*1)+(7*2)+(6*9)+(5*7)+(4*5)+(3*8)+(2*7)+(1*7)=176
176 % 10 = 6
So 129758-77-6 is a valid CAS Registry Number.

Synthesis and antimicrobial activity of brominated resorcinol dimers

Bouthenet, Elise,Oh, Ki-Bong,Park, Seungil,Nagi, Navjeet K.,Lee, Hyi-Seung,Matthews, Susan E.

experimental part, p. 7142 - 7145 (2012/01/13)

Dibrominated resorcinol dimers were synthesized by reaction of 4-bromoresorcinol with aldehydes under reflux in ethanol in the presence of HCl. Subsequent dehalogenation yielded the corresponding monobrominated compounds and a fully dehalogenated dimer. O

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.
