Check Digit Verification of cas no
The CAS Registry Mumber 144024-31-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,0,2 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 144024-31:
(8*1)+(7*4)+(6*4)+(5*0)+(4*2)+(3*4)+(2*3)+(1*1)=87
87 % 10 = 7
So 144024-31-7 is a valid CAS Registry Number.

Preparation of alkyl-substituted indoles in the benzene portion. Part 8. Improved practical synthesis of 4,4-dialkoxy-1-(1-arylsulfonyl-3-pyrrolyl)-1-butanone and 4-(1-arylsulfonyl-3-pyrrolyl)-4-oxobutanal, and a novel synthetic procedure for 4-alkoxyindole derivatives

Important precursors (1 and 2) for the synthesis of 4-substituted indole derivatives were readily obtained by acid treatment of a tosylamide (13), which was prepared in a single operation by treatment of 10 with N-tosyl-N',N'-dimethylformamidine (TsN=CHNMe2). Compound (10) was effectively synthesized from nitromethane and acrolein by way of a nitro compound (15). A novel indole formation reaction from the tosyl-amide (13) to gain short access to 4-alkoxyindoles, such as 16, 17, 19, and 21 is presented.
