The CAS Registry Mumber 33490-83-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,4,9 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 33490-83:
(7*3)+(6*3)+(5*4)+(4*9)+(3*0)+(2*8)+(1*3)=114
114 % 10 = 4
So 33490-83-4 is a valid CAS Registry Number.

Acylcarbodiimides, IV. Preparation and Some Reactions of Carbamoylcarbodiimides

Goerdeler, Joachim,Raddatz, Siegfried

, p. 1095 - 1105 (2007/10/02)

Starting from carbamoyl-thioureas (1) and with the aid of cyanuric trichloride/triethylamine several carbamoylcarbodiimides (2) were prepared.In the case of aryl-substituted 1, elimination of arylamine competed with that of hydrogen sulfide.Rearrangement of a guanyl isocyanate (6) formed in situ afforded 2a on another way.Many carbodiimides 2 add water and other protic nucleophiles very rapidly.The exact structure of the adducts 7 - 9 is discussed.
