Check Digit Verification of cas no

The CAS Registry Mumber 73455-05-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,4,5 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 73455-05:
127 % 10 = 7
So 73455-05-7 is a valid CAS Registry Number.

Development of a process for the preparation of chloromethyl chlorosulfate

Zheng, Bin,Sugiyama, Masano,Eastgate, Martin D.,Fritz, Alan,Murugesan, Saravanababu,Conlon, David A.

, p. 1827 - 1831 (2013/01/15)

A new and efficient synthesis of chloromethyl chlorosulfate (CMCS) from chloroiodomethane and chlorosulfonic acid is described. This process leverages a chlorosulfonic acid-mediated iodide oxidation to drive the equilibrating displacement process to full conversion. The resulting iodine byproduct is further oxidized and removed as iodate, to prevent iodide-induced decomposition of CMCS. This new process provides an efficient and scalable protocol for the preparation of CMCS in 92% solution yield and high purity (>99 GC area %).
