Check Digit Verification of cas no

The CAS Registry Mumber 69906-04-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,0 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 69906-04:
(7*6)+(6*9)+(5*9)+(4*0)+(3*6)+(2*0)+(1*4)=163
163 % 10 = 3
So 69906-04-3 is a valid CAS Registry Number.

Diastereoselective Synthesis of Novel Pyrrolidine or Pyrrolizine-Fused Benzo-δ-sultams via 1,3-Dipolar Cycloadditions

Ghandi, Mehdi,Kia, Maryam Asle,Sadeghzadegh, Masoud,Bozcheloei, Abolfazl Hasani,Kubicki, Maciej

, p. 1646 - 1653 (2015)

The synthesis of novel pyrrolidine or pyrrolizine-fused benzosultams is described. A number of (E)-N-(2-formylphenyl)-N-alkyl-2-phenylethenesulfonamides derivatives were synthesized and subjected to intramolecular [3+2] cycloaddition with azomethine ylides derived in situ from the reaction with sarcosine, phenylglycine, and L-proline.

Expedient synthesis of novel coumarin-based sulfonamides

Ghandi, Mehdi,Babazadeh, Elham

, p. 379 - 387 (2015/02/05)

The synthesis of novel coumarin-based sulfonamides was accomplished in good yields via InCl3-catalyzed three-component condensation of N-(2-formylphenyl)-N-methylbenzenesulfonamides, 4-hydroxycoumarin and cyclic secondary amines in toluene.
