25555-27-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25555-27-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,5,5 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 25555-27:
(7*2)+(6*5)+(5*5)+(4*5)+(3*5)+(2*2)+(1*7)=115
115 % 10 = 5
So 25555-27-5 is a valid CAS Registry Number.

We describe the preparation of 2-(dialkylhydrazone)-thioacetophenones starting from their oxygenated analogs. These compounds are used as building blocks in heterocyclic chemistry and lead to 3,4-dihydro-2H-1,4-thiazines or 2H-1,4-thiazines.
