Check Digit Verification of cas no

The CAS Registry Mumber 1449005-70-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,9,0,0 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1449005-70:
(9*1)+(8*4)+(7*4)+(6*9)+(5*0)+(4*0)+(3*5)+(2*7)+(1*0)=152
152 % 10 = 2
So 1449005-70-2 is a valid CAS Registry Number.

Total synthesis of (+)-heteroplexisolide E

Kutsumura, Noriki,Kiriseko, Akito,Saito, Takao

, p. 1367 - 1378 (2013/08/23)

Total synthesis of (+)-heteroplexisolide E has been demonstrated. The synthetic approach exploits the one-pot regioselective Negishi coupling (methylation) and transformation of a β-methallyl alcohol moiety to a branched prenyl group via palladium-catalyzed hydrogenolysis. For the introduction of the 4-oxo-pentylidene side chain, two independent methods were devised: olefin cross metathesis (CM) (route A) and aldol condensation (route B).
