Check Digit Verification of cas no

The CAS Registry Mumber 944913-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,9,1 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 944913-68:
(8*9)+(7*4)+(6*4)+(5*9)+(4*1)+(3*3)+(2*6)+(1*8)=202
202 % 10 = 2
So 944913-68-2 is a valid CAS Registry Number.

Chiral N-heterocyclic carbenes in natural product synthesis: Application of Ru-catalyzed asymmetric ring-opening/cross-metathesis and Cu-catalyzed allylic alkylation to total synthesis of baconipyrone C

Gillingham, Dennis G.,Hoveyda, Amir H.

, p. 3860 - 3864 (2008/02/14)

(Chemical Equation Presented) Chiral carbenes as major players: Two recently discovered chiral N-heterocyclic carbene (NHC) complexes play a crucial role in a concise enantioselective total synthesis of baconipyrone C (see scheme). An (NHC)Cu complex catalyzes a double asymmetric allylic alkylation (AAA), and an (NHC)Ru complex catalyzes an asymmetric ring-opening/cross- metathesis (AROM/CM) to establish the absolute configuration of the target. RCM = ring-closing metathesis.
