Check Digit Verification of cas no

The CAS Registry Mumber 1223441-22-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,3,4,4 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1223441-22:
(9*1)+(8*2)+(7*2)+(6*3)+(5*4)+(4*4)+(3*1)+(2*2)+(1*2)=102
102 % 10 = 2
So 1223441-22-2 is a valid CAS Registry Number.

The enantioselective intramolecular Morita-Baylis-Hillman reaction catalyzed by amino acid-derived phosphinothiourea

Gong, Jing-Jing,Yuan, Kui,Song, Hong-Liang,Wu, Xin-Yan

experimental part, p. 2439 - 2443 (2010/06/12)

A series of chiral bifunctional phosphinothioureas derived from l-amino acids have been developed to promote the enantioselective intramolecular Morita-Baylis-Hillman reaction. The process afforded the cyclic hydroxyl enones with up to 84% ee and good yields under mild conditions.
