Check Digit Verification of cas no

The CAS Registry Mumber 1536481-20-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,3,6,4,8 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1536481-20:
(9*1)+(8*5)+(7*3)+(6*6)+(5*4)+(4*8)+(3*1)+(2*2)+(1*0)=165
165 % 10 = 5
So 1536481-20-5 is a valid CAS Registry Number.

Amine-catalyzed asymmetric cross-aldol reactions using heterofunctionalized acetaldehydes as nucleophiles

Kano, Taichi,Sakamoto, Ryu,Maruoka, Keiji

supporting information, p. 944 - 947 (2014/03/21)

Various heterofunctionalized acetaldehydes were successfully employed in an amine-catalyzed asymmetric cross-aldol reaction, affording a variety of synthetically useful 1,2-difunctionalized compounds such as 1,2-diols and 1,2-aminoalcohols. With this method, both syn- and anti-1,2-difunctionalized compounds were obtained from the same set of reactants by using the appropriate amine catalyst.
