Check Digit Verification of cas no

The CAS Registry Mumber 134736-83-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,7,3 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134736-83:
(8*1)+(7*3)+(6*4)+(5*7)+(4*3)+(3*6)+(2*8)+(1*3)=137
137 % 10 = 7
So 134736-83-7 is a valid CAS Registry Number.

Asymmetric synthesis of abietane diterpenoids via B-alkyl Suzuki-Miyaura coupling. Formal total asymmetric synthesis of 12-deoxyroyleanone and cryptoquinone

Yajima, Arata,Yamaguchi, Ayumi,Saitou, Fumihiro,Nukada, Tomoo,Yabuta, Goro

, p. 1080 - 1084 (2007/10/03)

A convergent synthetic strategy for abietane diterpenoids via B-alkyl Suzuki-Miyaura coupling and Lewis acid-mediated cyclization reactions is established. Asymmetric total synthesis of 12-deoxyroyleanone, an antileishmanial diterpene, is described.

Preparative Bioorganic Chemistry, XV. - Preparation of Optically pure 2,4,4-Trimethyl-2-cyclohexen-1-ol, a New and Versatile Chiral Building Block in Terpene Synthesis

Mori, Kenji,Puapoomchareon, Prapai

, p. 1053 - 1056 (2007/10/02)

Enzymatic hydrolysis of (+/-)-2,4,4-trimethyl-2-cyclohexenyl acetate with pig liver esterase yielded (R)-(+)-2,4,4-trimethyl-2-cyclohexen-1-ol and unchanged (S)-(-)-acetate (S)-3.Enantiomerically pure (S)-2 was converted into (R)-dihydro
