Check Digit Verification of cas no

The CAS Registry Mumber 854817-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,4,8,1 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 854817-70:
(8*8)+(7*5)+(6*4)+(5*8)+(4*1)+(3*7)+(2*7)+(1*0)=202
202 % 10 = 2
So 854817-70-2 is a valid CAS Registry Number.

Gold-catalyzed cyclopenta- and cycloheptannulation cascades: A stereocontrolled approach to the scaffold of frondosins A and B

Garayalde, David,Krueger, Karolin,Nevado, Cristina

supporting information; experimental part, p. 911 - 915 (2011/03/19)

Golden cascades: Two diastereoselective gold-catalyzed cascade processes in which propargyl acetates react with alkenes or 1,4-dienes afford highly substituted five- and seven-membered rings, respectively (see scheme). The concerted nature of the gold-catalyzed Cope rearrangement has been used in the formal enantioselective synthesis of marine norsesquiterpenoids Frondosins A and B.
