Check Digit Verification of cas no

The CAS Registry Mumber 1431384-63-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,3,8 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1431384-63:
(9*1)+(8*4)+(7*3)+(6*1)+(5*3)+(4*8)+(3*4)+(2*6)+(1*3)=142
142 % 10 = 2
So 1431384-63-2 is a valid CAS Registry Number.

Study of asymmetric aldol and Mannich reactions catalyzed by proline-thiourea host-guest complexes in nonpolar solvents

Demir, Ayhan Sitki,Basceken, Sinan

, p. 515 - 525 (2013)

A proline-thiourea host-guest complex has been described as a good catalyst for asymmetric reactions such as aldol and Mannich reactions. High stereoselectivities were obtained under optimal conditions. Thiourea was observed to have an important effect on the reactivity and selectivity, even in an unconventional nonpolar reaction medium and without the need to utilize low temperatures. This proline-thiourea host-guest system has the ability to participate in a hydrogen bonding network.
