71412-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71412-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,4,1 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 71412-40:
(7*7)+(6*1)+(5*4)+(4*1)+(3*2)+(2*4)+(1*0)=93
93 % 10 = 3
So 71412-40-3 is a valid CAS Registry Number.

PROCESS FOR PREPARING ISOCYANATES BY THERMALLY CLEAVING CARBAMATES
-
Page/Page column 2-3, (2012/10/08)
A process is proposed for preparing isocyanates by thermally cleaving carbamates to obtain a carbamate cleavage gas comprising the corresponding isocyanate and the corresponding alcohol, which comprises quenching the carbamate cleavage gas in the presence of an ether which functions as an inhibitor for the reverse reaction of the isocyanate with the alcohol.
