1312938-57-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1312938-57-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,9,3 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1312938-57:
(9*1)+(8*3)+(7*1)+(6*2)+(5*9)+(4*3)+(3*8)+(2*5)+(1*7)=150
150 % 10 = 0
So 1312938-57-0 is a valid CAS Registry Number.

Concise, convergent syntheses of (±)-trichostatin a utilizing a Pd-catalyzed ketone enolate α-alkenylation reaction
Cosner, Casey C.,Helquist, Paul
, p. 3564 - 3567 (2011)
Two concise, convergent syntheses of (±)-trichostatin A (1), a potent histone deacetylase inhibitor, have been accomplished. The key step in both is a Pd-catalyzed α-alkenylation reaction between ketone 2 and either dienyl bromide 3 or alkenyl bromide 9 u
