Check Digit Verification of cas no

The CAS Registry Mumber 1558879-10-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,5,8,8,7 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1558879-10:
(9*1)+(8*5)+(7*5)+(6*8)+(5*8)+(4*7)+(3*9)+(2*1)+(1*0)=229
229 % 10 = 9
So 1558879-10-9 is a valid CAS Registry Number.

P-nitrophenyl ethylthioester in enantioselective organocatalytic Michael additions: Different behaviour of β-aryl and β-alkyl enals

Duce, Sara,Jorge, Maria,Alonso, Ines,Ruano, Jose Luis Garcia,Cid, M. Belen

, p. 7067 - 7075 (2013)

Although several nucleophiles derived from arylacetic acids have been described in catalysis via iminium activation, none have presented good enantioselectivity and reactivity with both β-alkyl and β-aryl enals. This study on the Michael addition of p-nit
