1269761-60-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1269761-60-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,7,6 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1269761-60:
(9*1)+(8*2)+(7*6)+(6*9)+(5*7)+(4*6)+(3*1)+(2*6)+(1*0)=195
195 % 10 = 5
So 1269761-60-5 is a valid CAS Registry Number.

Campestarenes: Novel shape-persistent Schiff base macrocycles with 5-fold symmetry
Guieu, Samuel,Crane, Angela K.,MacLachlan, Mark J.
supporting information; experimental part, p. 1169 - 1171 (2011/03/20)
A simple 1-step procedure yields a family of easily modifiable, stable, conjugated Schiff base macrocycles with 5-fold symmetry mediated by 3-center hydrogen bonding.
