Check Digit Verification of cas no

The CAS Registry Mumber 170450-78-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,4,5 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 170450-78:
(8*1)+(7*7)+(6*0)+(5*4)+(4*5)+(3*0)+(2*7)+(1*8)=119
119 % 10 = 9
So 170450-78-9 is a valid CAS Registry Number.

Asymmetric Synthesis of 2,3-Disubstituted Succinates via Chiral Oxazolidinone Controlled Displacement of α-Trifluoromethanesulfonate Substituted Esters

Decicco, Carl P.,Nelson, David J.,Corbett, Ronald L.,Dreabit, Jason C.

, p. 4782 - 4785 (1995)

The addition of chiral imides to α-trifluoromethanesulfonate esters gave chiral 2,3-disubstituted succinates with moderate to excellent diastereoselectivity and in good overall chemical yields.Both syn and anti chiral products are attainable via this methodology, with generally better diastereoselectivity and chemical yields observed in the production of the syn products.The reactions proceed through the predicted SN2 displacement of the triflate leaving group, as inferred from the absolute configuration of the products.
