Check Digit Verification of cas no

The CAS Registry Mumber 75697-69-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,6,9 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 75697-69:
(7*7)+(6*5)+(5*6)+(4*9)+(3*7)+(2*6)+(1*9)=187
187 % 10 = 7
So 75697-69-7 is a valid CAS Registry Number.

One pot synthesis of 3-nitro-1,2-dihydroxyanthraquinone and 1-hydroxy-9,10-dioxo-9,10-dihydroanthracen-2-yl benzoate using microwave irradiation

Jain, Khushboo,Singh, Sadhana

experimental part, p. 1395 - 1396 (2011/12/15)

An efficient method for the one pot synthesis of 3-nitro-1,2- dihydroxyanthraquinone and 1-hydroxy-9,10-dioxo-9,10-dihydroanthracen-2-yl benzoate (an anthraquinone derivative) under microwave irradiation conditions. The structures of newly synthesized compounds have been established by analytical data that includes elemental analysis, mass spectra, IR spectra and melting point.
