Check Digit Verification of cas no
The CAS Registry Mumber 1934-75-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,3 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1934-75:
(6*1)+(5*9)+(4*3)+(3*4)+(2*7)+(1*5)=94
94 % 10 = 4
So 1934-75-4 is a valid CAS Registry Number.

Page/Page column 6, (2008/06/13)
A process is described for preparing sodium dicyanamide, in which cyanamide is reacted simultaneously with sodium hydroxide solution and cyanogen chloride in aqueous solution at temperatures of 20 to 100° and a pH of 7.0 to 10.0. By means of the inventive process it is possible, starting from raw materials which are available in technical-grade quality, to prepare sodium dicyanamide in good yields of 75 to 95% and very high purities of up to 100% in a very environmentally friendly manner, for which reason this process is particularly highly suitable for the industrial scale.
