144831-29-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144831-29-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,8,3 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144831-29:
(8*1)+(7*4)+(6*4)+(5*8)+(4*3)+(3*1)+(2*2)+(1*9)=128
128 % 10 = 8
So 144831-29-8 is a valid CAS Registry Number.

Steric size in conformational analysis. Steric compression analyzed by circular dichroism spectroscopy
Boiadjiev,Lightner
, p. 11328 - 11339 (2000)
The relative steric size of methyl, ethyl, isopropyl, tert-butyl, phenyl, and benzyl groups has been determined from a sensitive tetrapyrrole model and exciton coupling circular dichroism (CD) measurements. Unlike the classical cyclohexane model, from whi
