The CAS Registry Mumber 139558-53-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,5 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139558-53:
(8*1)+(7*3)+(6*9)+(5*5)+(4*5)+(3*8)+(2*5)+(1*3)=165
165 % 10 = 5
So 139558-53-5 is a valid CAS Registry Number.

Synthesis of N-[1-acetyl-5-(D-arabino-tetraacetoxybutyl)-2-methyl-3-pyrrolylyl]-N-ph thalimidoacetamide

El Sadek,El Soccary

, p. 267 - 269 (1991)

5-(D-arabino- tetrahydroxybutyl)-2- methyl-3-pyrroylhydrazine (1) was treated with phthalic anhydride (2) to give N-[5-(D-arabino-tetrahydroxybutyl)- 2-methyl-3-pyrroylRB- o-carboxybenzoylhydrazine (4) in 85% yield; its i.r. spectrum showed C=O, CO2H, and NH and OH bands. Boiling this compound with acetic anhydride for 1 h afforded N-[1-acetly-2-methyl-3-pyrroyl-5- (D-arabino-tetraacetoxybutyl)]- N-phthalimidoacetamide (4).
