126235-13-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126235-13-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,2,3 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 126235-13:
(8*1)+(7*2)+(6*6)+(5*2)+(4*3)+(3*5)+(2*1)+(1*3)=100
100 % 10 = 0
So 126235-13-0 is a valid CAS Registry Number.

A Modified Synthesis of 4-Chromanones
Cox, Brian,Waigh, Roger D.
, p. 709 - 710 (2007/10/02)
Problems in the synthesis of 4-chromanones by condensation of 2-hydroxyacetophenones with formaldehyde can be avoided by the isolation of the Mannich base hydrochlorides and cyclization by titration with potassium hydroxide.
