Check Digit Verification of cas no

The CAS Registry Mumber 121787-54-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,7,8 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 121787-54:
(8*1)+(7*2)+(6*1)+(5*7)+(4*8)+(3*7)+(2*5)+(1*4)=130
130 % 10 = 0
So 121787-54-0 is a valid CAS Registry Number.

Iron-catalyzed tandem carbon-carbon/carbon-oxygen bond formation/aromatization of 2′-alkynyl-biphenyl-2-carbinols: A new approach to the synthesis of substituted phenanthrenes

Bera, Krishnendu,Sarkar, Soumen,Jana, Umasish

, p. 312 - 315 (2015)

An iron-catalyzed efficient synthesis of substituted phenanthrenes through tandem intramolecular C-C/C-O bond formations/aromatization of 2′-alkynyl-biphenyl-2-carbinols is reported. This method provides a novel, highly efficient, and straightforward rout

Sequential multiple-photon photochemistry of sterically congested enones

Schnapp, Karlyn A.,Motz, Philip L.,Stoeckel, Sharon M.,Wilson, R. Marshall,Krause Bauer, Jeanette A.,Bohne, Cornelia

, p. 2317 - 2320 (2007/10/03)

The photochemistry of sterically hindered enones 1 and 2 is described. A novel photorearrangement occurs in both systems which involves carbonyl attack on the adjacent phenyl ring, expansion of that ring to a cycloheptatriene and subsequent photochemically induced 1,7-phenyl migration.
