Check Digit Verification of cas no

The CAS Registry Mumber 1229806-01-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,9,8,0 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1229806-01:
(9*1)+(8*2)+(7*2)+(6*9)+(5*8)+(4*0)+(3*6)+(2*0)+(1*1)=152
152 % 10 = 2
So 1229806-01-2 is a valid CAS Registry Number.

Camphor-derived C1-symmetric chiral diamine organocatalysts for asymmetric Michael addition of nitroalkanes to enones

Zhou, Yirong,Liu, Qiang,Gong, Yuefa

, p. 7618 - 7627 (2012/10/29)

A series of stable C1-symmetric chiral diamines (2a-2l) were conveniently synthesized by condensing exo-(-)-bornylamine or (+)-(1S,2S,5R)-menthylamine with various commercially available Cbz-protected amino acids. Among them, 2a can efficiently promote the Michael addition of nitroalkanes to a broad scope of enones with high yields (up to 96%) and excellent enantioselectivities (up to 98%) under mild conditions.
