312534-71-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 312534-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,2,5,3 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 312534-71:
(8*3)+(7*1)+(6*2)+(5*5)+(4*3)+(3*4)+(2*7)+(1*1)=107
107 % 10 = 7
So 312534-71-7 is a valid CAS Registry Number.

Platinum-catalyzed α,β-unsaturated carbene formation in the formal syntheses of frondosin B and liphagal

Huynh, Khoi Q.,Seizert, Curtis A.,Ozumerzifon, Tarik J.,Allegretti, Paul A.,Ferreira, Eric M.

, p. 294 - 297 (2017/11/28)

Formal syntheses of tetracyclic terpenoids frondosin B and liphagal are described. Both synthetic routes rely on the use of platinum-catalyzed α,β-unsaturated carbene formation for the key C-C bond forming transformations. The successful route toward frondosin B utilizes a formal (4 + 3) cycloaddition, while the liphagal synthesis features the vinylogous addition of an enol nucleophile as a key step. Both synthetic routes are discussed, revealing insights into structural requirements in the catalytic a,β-unsaturated carbene reaction manifold.
