Check Digit Verification of cas no

The CAS Registry Mumber 175603-19-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,6,0 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 175603-19:
(8*1)+(7*7)+(6*5)+(5*6)+(4*0)+(3*3)+(2*1)+(1*9)=137
137 % 10 = 7
So 175603-19-7 is a valid CAS Registry Number.

Microwave induced selective bromination of 1,4-quinones and coumarins

Bansal, Vandana,Kanodia, Saraswati,Thapliyal, Prakash C.,Khanna, Rajinder N.

, p. 887 - 892 (2007/10/03)

Microwave irradiation accelerates the bromination of 1,4-quinones and coumarins with (i) bromide adsorbed on neutral alumina in 'dry media' and (ii) with iodine monobromide on acetic acid as compared to the reactions run at room temperature. Bromination takes place selectively at active quinonoid position in 1,4-quinones and at α,β-double bond in coumarins.
