Check Digit Verification of cas no

The CAS Registry Mumber 660441-29-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,0,4,4 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 660441-29:
(8*6)+(7*6)+(6*0)+(5*4)+(4*4)+(3*1)+(2*2)+(1*9)=142
142 % 10 = 2
So 660441-29-2 is a valid CAS Registry Number.

Alkyl [(Z)-4-dimethylaminomethylidene-5-oxo-1-phenyl-4,5-dihydro-1H-pyrazol-3-yl] acetate (4) was transformed with N- and C-nucleophiles into alkyl [4-(substituted amino)methylidene-4,5-dihydro-1H-pyrazol-3- yl] acetates (7) and alkyl (4-heteroarylmethylidene-4,5-dihydro-1H -pyrazol-3-yl)acetates (8), respectively. Compounds (7) cyclize by heating with DMFDMA in DMF into 2H-pyrazolo[4,3-c]pyridine-7-carboxylates (9).
