Check Digit Verification of cas no

The CAS Registry Mumber 1241977-52-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,1,9,7 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1241977-52:
(9*1)+(8*2)+(7*4)+(6*1)+(5*9)+(4*7)+(3*7)+(2*5)+(1*2)=165
165 % 10 = 5
So 1241977-52-5 is a valid CAS Registry Number.

Acid-base organocatalysts for the aza-Morita-Baylis-Hillman reaction of nitroalkenes

Takizawa, Shinobu,Horii, Atsushi,Sasai, Hiroaki

, p. 891 - 894 (2010)

A new class of acid-base chiral organocatalysts 1a and 2 for aza-Morita-Baylis-Hillman (aza-MBH) reaction of conjugated nitroalkenes is described. The acidic phenolic hydroxy groups and basic imidazole unit cooperatively activate nitroalkenes to promote the aza-MBH reaction in good yields with moderate enantioselectivities.
