Calculate Digit Verification of CAS Registry Number 191855-57:
(8*1)+(7*9)+(6*1)+(5*8)+(4*5)+(3*5)+(2*5)+(1*7)=169
169 % 10 = 9
So 191855-57-9 is a valid CAS Registry Number.

ARYLMETHYL ISOCYANATES

Kozhushko, B. N.,Lomakina, A. V.,Paliichuk, Yu. A.,Shokol, V. A.

, p. 654 - 660 (2007/10/02)

Chloromethyl isocyanate reacts readily with aromatic hydrocarbons in the presence of anhydrous ferric chloride or other catalysts of the Friedel-Crafts reaction with the formation of arylmethyl isocyanates.The latter add alcohols and amines readily, being converted into the corresponding substituted urethanes and ureas.When heated in the presence of catalytic amounts of 1,3-dimethylphosphol-3-ene they give substituted carbodiimides.
