Check Digit Verification of cas no
The CAS Registry Mumber 23550-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,5,5 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 23550-40:
(7*2)+(6*3)+(5*5)+(4*5)+(3*0)+(2*4)+(1*0)=85
85 % 10 = 5
So 23550-40-5 is a valid CAS Registry Number.

Thiomethylation of Propanone with a Mixture of Formaldehyde, Mercaptides, and Sodium Sulfide
Ulendeeva,Baeva,Galkin,Vasil'eva,Lyapina
, p. 197 - 202 (2007/10/03)
Thiomethylation of propanone with formaldehyde and sulfides of spent akaline solutions that contain predominantly sodium mercaptide is studied. It is demonstrated that thiomethylation results for the most part in a mixture of mono- and bis(methylthiomethyl)propan-2-ones (76 wt %) at 20°C and leads to the formation of 4-methyl-5-(methylthiomethyl)-7-thiabicyclo[3.3.1]non-3-en-2-one (52 wt %) and an increase in the fraction of tris- and tetrakis(methylthiomethyl)-substituted propanones at 80°C.
