Check Digit Verification of cas no

The CAS Registry Mumber 1403959-05-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,9,5 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1403959-05:
(9*1)+(8*4)+(7*0)+(6*3)+(5*9)+(4*5)+(3*9)+(2*0)+(1*5)=156
156 % 10 = 6
So 1403959-05-6 is a valid CAS Registry Number.

Organocatalyzed Baylis-Hillman reaction: An enantioselective approach

Thorat, Prashant B.,Goswami, Santosh V.,Khade, Bhimrao C.,Bhusare, Sudhakar R.

, p. 1320 - 1325 (2012/11/06)

A convenient protocol has been developed for the synthesis of Baylis-Hillman adducts in the presence of a base and an organocatalyst. We have designed and synthesized organocatalysts based on hydrogen bonding using a pyrrolidine ring as the backbone and applied them to Baylis-Hillman transformations. This method provides products in good to high yields (73-90%) and with excellent enantiomeric excesses (up to 96%) and reasonable reaction times.
