Calculate Digit Verification of CAS Registry Number 81464-91:
(7*8)+(6*1)+(5*4)+(4*6)+(3*4)+(2*9)+(1*1)=137
137 % 10 = 7
So 81464-91-7 is a valid CAS Registry Number.

Double-Head Haptens. Synthesis of and Experimentally Induced Contact Sensitivity to Substances Containing Two Unrelated Haptens, Pyrocatechol and α-Methylene-γ-butyrolactone, in the Same Molecule

Marchand, Bernard,Benezra, Claude

, p. 650 - 653 (1982)

A "double-head" hapten containing a pyrocatechol and an α-methylene-γ-butyrolactone moiety (3) and "monofunctional haptens" with either one of these moietes (18 and 19) connected by a six-carbon chain have been synthesized, and their sensitizing capacity
