Check Digit Verification of cas no

The CAS Registry Mumber 128250-50-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,5 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128250-50:
(8*1)+(7*2)+(6*8)+(5*2)+(4*5)+(3*0)+(2*5)+(1*0)=110
110 % 10 = 0
So 128250-50-0 is a valid CAS Registry Number.

Regioselective synthesis of 2-arylidene coumaran-3-ones by dye-sensitized photooxygenation of 2-hydroxyphenyl-styrylketones in the presence of sodium dodecyl sulphate

Chawla, H. Mohindra,Sharma, S. Kumar

, p. 1611 - 1624 (1990)

2′-Hydroxyphenylstyrylketones when subjected to dye- sensitized photooxygenation in the presence of sodium dodecylsulphate (8x × 10-3M) in methanol, yielded the corresponding oxidatively cyclized products, i.e., 2-aryl idenecoumaran 3-ones and
