213919-30-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 213919-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,9,1 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 213919-30:
(8*2)+(7*1)+(6*3)+(5*9)+(4*1)+(3*9)+(2*3)+(1*0)=123
123 % 10 = 3
So 213919-30-3 is a valid CAS Registry Number.

Long-range chiral induction in chemical systems with helical organization. Promesogenic monomers in the formation of poly(isocyanide)s and in the organization of liquid crystals

Amabilino, David B.,Ramos, Elena,Serrano, José-Luis,Sierra, Teresa,Veciana, Jaume

, p. 9126 - 9134 (2007/10/03)

The preparation of optically active poly(isocyanide)s derived from chiral promesogenic monomers is reported. Remarkably, the stereogenic carbon atom in the monomer is able to pass its chiral 'information' to the growing polymer backbone which is at least
