The CAS Registry Mumber 107953-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,9,5 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 107953-90:
(8*1)+(7*0)+(6*7)+(5*9)+(4*5)+(3*3)+(2*9)+(1*0)=142
142 % 10 = 2
So 107953-90-2 is a valid CAS Registry Number.

4-NITROPYROCATECHOL ETHERS AS POSSIBLE PHOTOAFFINITY LABELS. PHOTOCHEMICAL REACTIONS OF 4-NITROPYROCATECHOL ETHERS OF BIOLOGICALLY ACTIVE COMPOUNDS

Castello, A.,Cervello, J.,Marquet, J.,Moreno-Manas, M.,Sirera, X.

, p. 4073 - 4082 (2007/10/02)

The photochemical reactions of O- and N-(2-methoxy-4-nitro)phenoxyalkyl derivatives of estrone and of the antibiotic cycloheximide with methylamine afford clean substitutions of the methoxy group.From these experiments it is inferred that 2-methoxy-4-nitrophenyl ethers can be good photoaffinity labels.
