Check Digit Verification of cas no

The CAS Registry Mumber 1397266-40-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,7,2,6 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1397266-40:
(9*1)+(8*3)+(7*9)+(6*7)+(5*2)+(4*6)+(3*6)+(2*4)+(1*0)=198
198 % 10 = 8
So 1397266-40-8 is a valid CAS Registry Number.

Squaramide-catalysed enantio- and diastereoselective sulfa-Michael addition of thioacetic acid to α,β-disubstituted nitroalkenes

Yang, Wen,Du, Da-Ming

, p. 6876 - 6884 (2012)

A highly enantio- and diastereoselective sulfa-Michael addition of thioacetic acid to α,β-disubstituted nitroalkenes catalysed by a chiral squaramide organocatalyst has been described. This organocatalytic reaction at an extremely low catalyst loading (0.2 mol%) furnished synthetically useful β-nitro sulfides in excellent yields with good diastereoselectivities and high enantioselectivities (up to 94:6 dr, 95% ee). In addition, the catalytic reaction can be performed on a 10 gram scale, and facile transformation into taurine derivative is also presented.
