Check Digit Verification of cas no

The CAS Registry Mumber 916445-70-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,4,4 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 916445-70:
(8*9)+(7*1)+(6*6)+(5*4)+(4*4)+(3*5)+(2*7)+(1*0)=180
180 % 10 = 0
So 916445-70-0 is a valid CAS Registry Number.

Synthetic studies on perophoramidine and the communesins: Construction of the vicinal quaternary stereocenters

Seo, Jae Hong,Artman III, Gerald D.,Weinreb, Steven M.

, p. 8891 - 8900 (2007/10/03)

An efficient synthetic strategy for installation of the two vicinal quaternary carbon centers of the communesins is reported. Key steps include the O-allylation/Claisen rearrangement of spirolactone systems, which are formed by tandem intramolecular Heck cyclization/carbonylation. Substituent and solvent effects on the stereochemical outcome of the Claisen rearrangements have been examined. The stereochemical assignment of the allyl spirolactone previously reported as 17 has now been revised to 31, which has the communesin relative configuration at the quaternary carbons. Key C-allyl spirolactone 59 bearing functional handles required for the communesin core has been constructed with a 9.8:1 diastereomer ratio.
