Check Digit Verification of cas no

The CAS Registry Mumber 84384-14-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,3,8 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 84384-14:
(7*8)+(6*4)+(5*3)+(4*8)+(3*4)+(2*1)+(1*4)=145
145 % 10 = 5
So 84384-14-5 is a valid CAS Registry Number.

About the Preparation and Chlorination of Carbonyl Diisothiocyanate

Bunnenberg, Rolf,Jochims, Johannes C.,Haerle, Helmut

, p. 3587 - 3596 (2007/10/02)

An improved preparation of carbonyl diisothiocyanate (1) is described.Compound 1 can be stored in form of its stable hydrochloride 3.Depending on the reaction conditions chlorination of 1 leads to the acyl isocyanide dichlorides 5 or 8.Compound 5 reacts with amines to give: the triazines 9a - c, the ammelines 11a, b, the guanidines 12 and 16a, or the acylcarbodiimides 14 and 15.With sodium phenolate 5 forms the dialkylidene urea 17, and with thiolates the derivatives 18a - c of dithiocarbonic acid.Compound 8 racts with thiophenolate to give 19 and with tert-butylamine to yield the carbamoylcarbodiimide 20.
