Check Digit Verification of cas no

The CAS Registry Mumber 31139-98-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,1,3 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 31139-98:
(7*3)+(6*1)+(5*1)+(4*3)+(3*9)+(2*9)+(1*8)=97
97 % 10 = 7
So 31139-98-7 is a valid CAS Registry Number.

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.
