Check Digit Verification of cas no

The CAS Registry Mumber 1211565-16-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,1,5,6 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1211565-16:
(9*1)+(8*2)+(7*1)+(6*1)+(5*5)+(4*6)+(3*5)+(2*1)+(1*6)=110
110 % 10 = 0
So 1211565-16-0 is a valid CAS Registry Number.

Squaramide-catalyzed enantioselective michael addition of diphenyl phosphite to nitroalkenes

Zhu, Ye,Malerich, Jeremiah P.,Rawal, Viresh H.

, p. 153 - 156 (2010)

chemical equation presented Michael's a square: An easily prepared squaramide catalyst that promotes the highly enantioselective Michael addition reaction of diphenyl phosphite to a range of nitroalkenes is described. This method leads to chiral β-nitro phosphonates, which are precursors to biologically active β-amino phosphonic acids.
