Check Digit Verification of cas no

The CAS Registry Mumber 1564223-81-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,4,2,2 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1564223-81:
(9*1)+(8*5)+(7*6)+(6*4)+(5*2)+(4*2)+(3*3)+(2*8)+(1*1)=159
159 % 10 = 9
So 1564223-81-9 is a valid CAS Registry Number.

The development of carbon-carbon bond forming reactions of aminal radicals

Schiedler, David A.,Vellucci, Jessica K.,Lu, Yi,Beaudry, Christopher M.

, p. 1448 - 1465 (2015/02/19)

Aminal radicals were generated and used in synthetic reactions for the first time. Aminal radicals are formed from aminals by radical translocation using AIBN and a stoichiometric hydrogen atom donor, or by SmI2 reduction of N-acyl amidines or amidinium ions in the presence of a proton source. Aminal radicals were found to participate in inter- and intramolecular C-C bond forming reactions with electron deficient alkenes. Chemical yields were as high as 99%.
