Check Digit Verification of cas no

The CAS Registry Mumber 1383675-98-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,3,6,7 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1383675-98:
(9*1)+(8*3)+(7*8)+(6*3)+(5*6)+(4*7)+(3*5)+(2*9)+(1*8)=206
206 % 10 = 6
So 1383675-98-6 is a valid CAS Registry Number.

Phosphine-phosphite ligands: Chelate ring size vs. activity and enantioselectivity relationships in asymmetric hydrogenation

Farkas, Gergely,Balogh, Szabolcs,Madarasz, Jozsef,Szoellsy, Aron,Darvas, Ferenc,Uerge, Laszlo,Gouygou, Maryse,Bakos, Jozsef

experimental part, p. 9493 - 9502 (2012/09/11)

A series of new phosphine-phosphite ligands P(C)nOP (n = 1-4) have been synthesized and used for rhodium-catalyzed asymmetric hydrogenation of prochiral olefins in order to study the effect of the chelate ring size. Excellent ees (up to 97.5%) were obtained in the hydrogenation of dimethyl itaconate and an increase of activity and enantioselectivity was observed in the hydrogenation of (Z)-α-acetamidocinnamic acid methyl ester with the increasing length of the backbone of the ligands.
