Check Digit Verification of cas no

The CAS Registry Mumber 84289-19-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,8 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 84289-19:
(7*8)+(6*4)+(5*2)+(4*8)+(3*9)+(2*1)+(1*9)=160
160 % 10 = 0
So 84289-19-0 is a valid CAS Registry Number.

Selective ruthenium-catalyzed three-component synthesis of pyrroles

Zhang, Min,Neumann, Helfried,Beller, Matthias

supporting information, p. 597 - 601 (2013/02/23)

It's a snap: A novel catalytic three-component coupling reaction using simple and easily available substrates leads to a wide range of substituted pyrroles with high regioselectively (see scheme; Xantphos=9,9-dimethyl-4,5- bis(diphenylphosphino)xanthene). Copyright

FORMATION OF 1,2,3,5-TERASUBSTITUTED 2-PYRROLIN-4-ONES AND 1,2,3-TRISUBSTITUTED PYRROLES FROM DIPHENYLCYCLOPROPENONE AND 1,4-DIAZABUTADIENES

Takahashi, Masahiko,Funaki, Tomomi,Honda, Hisao,Yokoyama, Yoshiyuki,Takimoto, Hideo

, p. 1921 - 1924 (2007/10/02)

The reaction of diphenylcyclopropenone (1) with 1,4-diaryl-1,4-diazabutadienes (2) afforded 1-aryl-5-(N-aryl) iminomethyl-2,3-diphenyl-2-pyrrolin-4-ones (3) as major products and 1-aryl-2,3-diphenylpyrroles (11) as minor products.
