42172-24-7 Usage
Preparation
To an ice-cooled dry flask containing 25.0 gm (0.18 mole) of s-trithiane is slowly added dry chlorine gas. As soon as the solid liquefies, the temperature is raised to 10-20°C, and approximately a total of 57.0 gm (0.80 mole) of chlorine gas is absorbed. The product is distilled under reduced pressure to afford 9.9-12.9 gm (46-60%), b.p. 30°C (10 mm Hg).
Check Digit Verification of cas no
The CAS Registry Mumber 42172-24-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,1,7 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 42172-24:
(7*4)+(6*2)+(5*1)+(4*7)+(3*2)+(2*2)+(1*4)=87
87 % 10 = 7
So 42172-24-7 is a valid CAS Registry Number.
