Check Digit Verification of cas no

The CAS Registry Mumber 238079-40-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,8,0,7 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 238079-40:
(8*2)+(7*3)+(6*8)+(5*0)+(4*7)+(3*9)+(2*4)+(1*0)=148
148 % 10 = 8
So 238079-40-8 is a valid CAS Registry Number.

Novel heteroatom containing rubyrins

Srinivasan, Alagar,Pushpan, Simi K.,Ravikumar, Murugaeson,Chandrashekar, Tavarekere K.,Raja, Roy

, p. 6671 - 6680 (2007/10/03)

Synthesis of rubyrins containing two or three heteroatoms (O, S, Se) in the core is accomplished using modified diols and tetrapyrromethanes. Substitution of heteroatoms leads to significant reductions in HOMO-LUMO gap and easier oxidations and reductions reflecting the changes in electronic structure of the rubyrin skeleton.
