Check Digit Verification of cas no

The CAS Registry Mumber 887623-58-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,7,6,2 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 887623-58:
(8*8)+(7*8)+(6*7)+(5*6)+(4*2)+(3*3)+(2*5)+(1*8)=227
227 % 10 = 7
So 887623-58-7 is a valid CAS Registry Number.

A 2-thiocyano HYPNONE derivatives method for the preparation of

-

Paragraph 0127-0134, (2016/10/10)

The invention discloses a method for preparing 2-sulfur cyano acetophenone derivatives. The method for preparing the 2-sulfur cyano acetophenone derivatives comprises the following steps: dissolving styrene derivatives and ammonium thiocyanate in a solvent, and reacting at 20-30 DEG C to obtain 2-sulfur cyano acetophenone derivatives. According to the method for preparing the 2-sulfur cyano acetophenone derivatives, the styrene derivatives are taken as starting materials; the raw materials are easily available and various in type; products prepared by the method have various in type, can be directly used and can also be used for other further reactions; meanwhile, the method is mild in reaction conditions and simple in reaction operation and post-processing process; an accelerant does not need to be added; the production process meets the green and chemical requirements, is relatively high in yield and is suitable for large-scale production.
