Check Digit Verification of cas no

The CAS Registry Mumber 26906-85-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,9,0 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 26906-85:
(7*2)+(6*6)+(5*9)+(4*0)+(3*6)+(2*8)+(1*5)=134
134 % 10 = 4
So 26906-85-4 is a valid CAS Registry Number.

Synthesis and structural characterisation of ring B oxidised derivatives of dehydroabietic acid

Monteiro,Silvestre,Silva,Cavaleiro,Felix,Drew

, p. 1091 - 1097 (2001)

The synthesis and structural characterisation of some new derivatives of dehydroabietic acid, oxidised in the 6 and 7 positions of ring B, are described. Other known derivatives were exhaustively characterised for the first time and the previous NMR assig

FORMATION OF COLEON A SKELETON FROM (-)-ABIETIC ACID

Matsumoto, Takashi,Imai, Sachihiko,Ondo, Kenji,Takeyama, Nobuaki,Fukui, Kenji

, p. 425 - 428 (2007/10/02)

By the treatment of Δ6-6-hydroxy-5βH-dehydroabietic acid (18-6)-lactone with potassium hydrogensulfate or conc. sulfuric acid, the B ring aromatization and the C1-C10 bond cleavage occurred to give 1,10-secoabietane derivatives possessing coleon A skeleton.
