1266348-23-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1266348-23-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,6,3,4 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1266348-23:
(9*1)+(8*2)+(7*6)+(6*6)+(5*3)+(4*4)+(3*8)+(2*2)+(1*3)=165
165 % 10 = 5
So 1266348-23-5 is a valid CAS Registry Number.

Synthesis and characterization of novel unnatural bichalcones
Gurung, Santosh K.,Kim, Soo Bae,Park, Haeil
, p. 1919 - 1926 (2012/01/05)
Five bichalcones (5-1 ~ 5-4, 9) were prepared by the reaction of biphenyl-4,4′-dicarbaldehyde (4) and 4,4′-dioxybenzaldehyde (8) with the respective acetophenone analogs via Claisen-Schmidt condensation and were then fully identified by 1H-NMR, 13C-NMR and mass analyses.
