Check Digit Verification of cas no

The CAS Registry Mumber 50585-12-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,5,8 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 50585-12:
(7*5)+(6*0)+(5*5)+(4*8)+(3*5)+(2*1)+(1*2)=111
111 % 10 = 1
So 50585-12-1 is a valid CAS Registry Number.

Control of regioselectivity by the lone substituent through steric and electronic effects in the nitrosoarene ene reaction of deuterium-labeled trisubstituted alkenes

Adam, Waldemar,Krebs, Oliver,Orfanopoulos, Michael,Stratakis, Manolis

, p. 8395 - 8399 (2007/10/03)

For the ene reaction of 4-nitronitrosobenzene (ARNO) with a variety of primary and secondary lone alkyl-substituted substrates, the twix/twin regioselectivity is constant at about 85:15. In contrast, for the lone tert-butyl group and for lone aryl substituents, the twix regioisomer is obtained exclusively. These regioselectivities have been rationalized in terms of steric interactions and coordination between the enophile and the substrates in the transition states of the first reaction step.
