124530-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124530-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,5,3 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 124530-98:
(8*1)+(7*2)+(6*4)+(5*5)+(4*3)+(3*0)+(2*9)+(1*8)=109
109 % 10 = 9
So 124530-98-9 is a valid CAS Registry Number.

Synthesis and Reactions of 1-Acetyl-2-benzylidene-3-oxo-2,3-dihydroindoles
Buzas, A.,Merour, J. Y.
, p. 458 - 461 (2007/10/02)
1-Acetyl-3-oxo-2,3-dihydroindoles were reacted with substituted benzaldehydes affording 1-acetyl-2-arylmethylene-3-oxo-2,3-dihydroindoles which were selectively reduced by hydrogen; then a Horner-Emmons reaction gave the precursors of 2-substituted trypta
