Check Digit Verification of cas no

The CAS Registry Mumber 1285718-90-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,5,7,1 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1285718-90:
(9*1)+(8*2)+(7*8)+(6*5)+(5*7)+(4*1)+(3*8)+(2*9)+(1*0)=192
192 % 10 = 2
So 1285718-90-2 is a valid CAS Registry Number.

Asymmetric C-C bond formation via Darzens condensation and Michael addition using monosaccharide-based chiral crown ethers

Bakó, Péter,Rapi, Zsolt,Keglevich, Gy?rgy,Szabó, Tamás,Sóti, Péter L.,Vígh, Tamás,Grn, Alajos,Holczbauer, Tamás

, p. 1473 - 1476 (2011)

Liquid-liquid phase asymmetric Darzens condensations were promoted by d-glucose- and d-mannose-based crown ethers. The corresponding aromatic and heteroaromatic α,β-epoxyketones were obtained with moderate to high enantioselectivities (up to 96%) as well
