Check Digit Verification of cas no
The CAS Registry Mumber 812-94-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,1 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 812-94:
(5*8)+(4*1)+(3*2)+(2*9)+(1*4)=72
72 % 10 = 2
So 812-94-2 is a valid CAS Registry Number.

Process for preparing fluorochemical monoisocyanates
-
Page/Page column 3, (2010/02/12)
A process for preparing fluorochemical monoisocyanates comprises reacting at least one fluorochemical alcohol represented by the formula CnF2n+1SO2NCH3(CH2)mOH, wherein n=2 to 5, and m=2 to 4, with 4,4′-diphenylmethane diisocyanate (MDI) in a solvent in which the resulting fluorochemical monoisocyanate is not soluble; wherein the molar ratio of fluorochemical alcohol:MDI is from about 1:1 to about 1:2.5.
