Check Digit Verification of cas no

The CAS Registry Mumber 1579998-97-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,9,9,9 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1579998-97:
(9*1)+(8*5)+(7*7)+(6*9)+(5*9)+(4*9)+(3*8)+(2*9)+(1*7)=282
282 % 10 = 2
So 1579998-97-2 is a valid CAS Registry Number.

Photoswitchable thioureas for the external manipulation of catalytic activity

Osorio-Planes, Laura,Rodriguez-Escrich, Carles,Pericas, Miquel A.

, p. 1704 - 1707 (2014/04/17)

A series of azobenzene-based thiourea catalysts have been developed with the aim of achieving control over the catalytic activity by the use of light. The conceptual design of these systems relies on the inactivation by means of intramolecular hydrogen bonding, only likely to take place in one of their isomeric forms. After fine structure modulation of the catalyst a substantial difference in activity has been observed between the irradiated and the nonirradiated reaction. Furthermore, the system allowed in situ manipulation of the catalyst activity during the course of a given experiment.
