Check Digit Verification of cas no
The CAS Registry Mumber 2188-09-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,8 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2188-09:
(6*2)+(5*1)+(4*8)+(3*8)+(2*0)+(1*9)=82
82 % 10 = 2
So 2188-09-2 is a valid CAS Registry Number.

TWO-STEP AND ONE-POT PROCESSES FOR PREPARATION OF ALIPHATIC DIISOCYANATES
-
Paragraph 0117, (2017/02/02)
The present invention relates to using a two-step (thermolysis) or one-pot process to prepare aliphatic diisocyanates from aliphatic diamines and diaryl carbonates. Polyisocyanates can also be prepared from polyamines and diaryl carbonates. The present synthetic processes do not apply phosgene or highly toxic reagents and chloro-solvents during the entire procedure.
