Check Digit Verification of cas no

The CAS Registry Mumber 1318698-20-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,8,6,9 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1318698-20:
(9*1)+(8*3)+(7*1)+(6*8)+(5*6)+(4*9)+(3*8)+(2*2)+(1*0)=182
182 % 10 = 2
So 1318698-20-2 is a valid CAS Registry Number.

Chiral (acyclic diaminocarbene)gold(I)-catalyzed dynamic kinetic asymmetric transformation of propargyl esters

Wang, Yi-Ming,Kuzniewski, Christian N.,Rauniyar, Vivek,Hoong, Christina,Toste, F. Dean

, p. 12972 - 12975 (2011/10/08)

A highly enantioselective transformation catalyzed by chiral (acyclic diaminocarbene)gold(I) complexes is reported. The enantioselective synthesis of 2-substituted chromenyl pivalates from racemic phenol-substituted propargyl pivalates was developed. Rearrangement of the substrates in the presence of cationic gold gave allene intermediates, whose cyclization resulted in formation of enantioenriched product through a dynamic kinetic asymmetric transformation.
