Check Digit Verification of cas no

The CAS Registry Mumber 588729-98-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,8,8,7,2 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 588729-98:
(8*5)+(7*8)+(6*8)+(5*7)+(4*2)+(3*9)+(2*9)+(1*8)=240
240 % 10 = 0
So 588729-98-0 is a valid CAS Registry Number.

Oxidative cyclization of N-methyl- and N-benzoylpyridylthioureas. Preparation of new thiazolo[4,5-b] and [5,4-b]pyridine derivatives

Jouve, Karine,Bergman, Jan

, p. 261 - 268 (2007/10/03)

Cyclization of N-methyl- and N-benzoylpyridylthioureas, prepared from the corresponding aminopyridines, has been realized using various conditions. With bromine in acetic acid or potassium ferricyanide, the cyclization occurred on the nitrogen of the pyridine ring and pyridinium salts or 1,2,4-thiadiazolo[2,3-a]pyridylidene systems were obtained. On the other hand, treatment of the thioureas with sodium methoxide in N-methylpyrrolidinone (NMP) led to formation of thiazolo[4,5-b] and [5,4-b]pyridines, which are interesting targets for biological evaluation.
