Check Digit Verification of cas no

The CAS Registry Mumber 1229029-89-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,9,0,2 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1229029-89:
(9*1)+(8*2)+(7*2)+(6*9)+(5*0)+(4*2)+(3*9)+(2*8)+(1*9)=153
153 % 10 = 3
So 1229029-89-3 is a valid CAS Registry Number.

Stereoselective syntheses of four diastereomers of 3,9,12- trihydroxycalamenene via a benzobicyclo[3.3.1] intermediate

Sun, Yongquan,Yu, Binxun,Wang, Xiaolei,Tang, Shibing,She, Xuegong,Pan, Xinfu

, p. 4224 - 4229 (2010)

The highly stereoselective syntheses of four diastereomers of natural 3,9,12-trihydroxycalamenene are described. The syntheses highlight the utility of an unusual framework of benzobicyclo[3.3.1] lactones, which were accomplished via an intramolecular Friedel-Crafts-type Michael addition of α,β-unsaturated lactones.
