Chemical Properties

2,4,6-Trimethyldihydro-4H-1,3,5-dithiazine has a roasted, meaty odor.

Preparation

Reportedly prepared in a patented process by reacting the first aldehyde group with aqueous ammonia in a mixture of acetaldehyde and alkanal (C4-C6) and reacting the resulting Schiff base with hydrogen sulfide.

Check Digit Verification of cas no

The CAS Registry Mumber 638-17-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 638-17:
(5*6)+(4*3)+(3*8)+(2*1)+(1*7)=75
75 % 10 = 5
So 638-17-5 is a valid CAS Registry Number.
