Check Digit Verification of cas no

The CAS Registry Mumber 260411-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,0,4,1 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 260411-23:
(8*2)+(7*6)+(6*0)+(5*4)+(4*1)+(3*1)+(2*2)+(1*3)=92
92 % 10 = 2
So 260411-23-2 is a valid CAS Registry Number.

Use of 1,2-dichloro 4,5-dicyanoquinone (DDQ) for cleavage of the 2- naphthylmethyl (NAP) group

Xia, Jie,Abbas, Saeed A.,Locke, Robert D.,Piskorz, Conrad F.,Alderfer, James L.,Matta, Khushi L.

, p. 169 - 173 (2007/10/03)

The 2-naphthylmethyl (NAP) group is a versatile group for protection of hydroxyl functions. It is stable to 4% TFA in CHCl3, hot 80% HOAc-H2O, SnCl2-AgOTf and HCl-EtOH, but it can readily be removed with DDQ in CH2Cl2.
