Check Digit Verification of cas no

The CAS Registry Mumber 104413-34-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,4,1 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 104413-34:
(8*1)+(7*0)+(6*4)+(5*4)+(4*1)+(3*3)+(2*3)+(1*4)=75
75 % 10 = 5
So 104413-34-5 is a valid CAS Registry Number.

Dichloromeldrum's acid (DiCMA): A practical and green amine dichloroacetylation reagent

Heard, David M.,Lennox, Alastair J.J.

supporting information, p. 3368 - 3372 (2021/05/06)

Dichloromeldrum's acid is introduced as a bench-stable, nonvolatile reagent for the dichloroacetylation of anilines and alkyl amines to produce α,α-dichloroacetamides, which are important motifs for medicinal chemistry. Products are formed in good to excellent yields with reagent grade solvents, and, as the only byproducts are acetone and CO2, no column chromatography is required. Thus, this reagent is practical, efficient, and green for the dichloroacetylation of primary amines.
