Check Digit Verification of cas no

The CAS Registry Mumber 121802-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,8,0 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 121802-89:
(8*1)+(7*2)+(6*1)+(5*8)+(4*0)+(3*2)+(2*8)+(1*9)=99
99 % 10 = 9
So 121802-89-9 is a valid CAS Registry Number.

Fused Heterocycles. Part 3. Synthesis and Stereochemistry of Benzopyrano- and Benzothiapyrano-Pyrazoles

Toth, Gabor,Szoelloesy, Aron,Lorand, Tamas,Konya, Tibor,Szabo, Dezsoe,et al.

, p. 319 - 324 (2007/10/02)

Several tricyclic benzopyranopyrazole derivatives have been studied by 1H and 13C n.m.r. spectroscopy.They were prepared by treating 3-benzylidene-chromanones and -1-thiochromanones with semicarbazide or thiosemicarbazide: reactions which give only the cis-3-H,3a-H stereoisomers.
