Check Digit Verification of cas no

The CAS Registry Mumber 107089-92-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,0,8 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 107089-92:
(8*1)+(7*0)+(6*7)+(5*0)+(4*8)+(3*9)+(2*9)+(1*2)=129
129 % 10 = 9
So 107089-92-9 is a valid CAS Registry Number.

Benzopyrans: Part XX - 4-Oxo-4H-benzopyran-3-carbonitrile/Carboxylic Acid: Change of Their Reaction Courses by a Methyl Substituent at 2-Position

Ghosh, Chandra Kanta,Pal, Chandana

, p. 1288 - 1290 (2007/10/02)

2-Methyl-4-oxo-4H-benzopyran-3-carbonitriles (1b) and the corresponding carboxylic acids (2b), unlike their 2-unsubstituted analogues (1a) and (2a), give with phenyl hydrazine the hydrazones (6b) and the pyrazoles (13b), respectively.The hydrazones (6b) have been converted into the benzopyranopyrazoles (8b).
