Check Digit Verification of cas no

The CAS Registry Mumber 126983-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,9,8 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 126983-40:
(8*1)+(7*2)+(6*6)+(5*9)+(4*8)+(3*3)+(2*4)+(1*0)=152
152 % 10 = 2
So 126983-40-2 is a valid CAS Registry Number.

N-SUBSTITUTED HYDROXYSUCCINIMIDES FROM (S)-MALIC ACID AS NEW REAGENTS FOR ASYMMETRIC DIELS-ALDER ADDITION TO ENOATES

Poll, T.,Hady, A. F. Abdel,Karge, R.,Linz, G.,Weetman, J.,Helmchen, G.

, p. 5595 - 5598 (1989)

(S)-N-Methyl-2-hydroxysuccinimide, easily available from natural (S)-malic acid, supplements the previously introduced (R)-pantolactone as chiral auxiliary for asymmetric Diels-Alder reactions of enoates, but yields products of opposite configuration.Practical large-scale preparations of enantiomer pairs of synthetically important Diels-Alder adducts, including adducts from crotonates, are described.

ASYMMETRIC DIELS-ALDER REACTIONS: EPC-SYNTHESIS OF A STABLE SARKOMYCIN PRECURSOR (CYCLOSARKOMYCIN)

Linz, Guenter,Weetman, John,Hady, A. F. Abdel,Helmchen, Guenter

, p. 5599 - 5602 (2007/10/02)

The first synthesis of enantiomerically pure cyclosarkomycin, a stable, crystaline precursor of the antitumor agent sarkomycin is reported.Key steps are an asymmetric Diels-Alder reaction of the (E)-3-bromoacrylate of (R)-pantolactone and introduction of oxygen funtionality via elimination/β-addition.The synthesis of cyclosarkomycin was accomplished in 9 steps in 17 percent overall yield.
