Check Digit Verification of cas no

The CAS Registry Mumber 1242167-47-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,1,6 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1242167-47:
(9*1)+(8*2)+(7*4)+(6*2)+(5*1)+(4*6)+(3*7)+(2*4)+(1*7)=130
130 % 10 = 0
So 1242167-47-0 is a valid CAS Registry Number.

Total synthesis of (±)-bruguierol A via an intramolecular [3+2] cycloaddition of cyclopropane 1, 1-diester

Hu, Bao,Xing, Siyang,Ren, Jun,Wang, Zhongwen

experimental part, p. 5671 - 5674 (2010/10/02)

Total synthesis of natural product (±)-bruguierol A was accomplished in 10-steps and with an overall 16.8% yield. The embedded unique 8-oxabicyclo[3.2.1]octane core skeleton in this natural product was constructed via a novel Sc(OTf)3-catalyzed intramolecular [3+2] cycloaddition of cyclopropane which was developed recently in this laboratory. This general synthetic strategy can be potentially applied to the synthesis of a broad range of structurally related natural products.
