126291-41-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126291-41-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,2,9 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 126291-41:
(8*1)+(7*2)+(6*6)+(5*2)+(4*9)+(3*1)+(2*4)+(1*1)=116
116 % 10 = 6
So 126291-41-6 is a valid CAS Registry Number.

SYNTHESIS AND PHOTOCHEMICAL REACTIONS OF NITROESTROGENS: POSSIBLE PHOTOAFFINITY LABELS OF ZERO LENGTH
Marquet, Jorge,Cantos, Albert,Teixido, Monica,Moreno-Manas, Marcial
, p. 441 - 452 (1989)
The syntheses of 3,4-dimethoxy-1,3,5(1O)-estratrien-17-one and 4-bromo-3-methoxy-2-nitro-1,3,5(10)-estratrien-17-one are described and their photoreactions with amines and hydroxide ion studied.The possible usefulness of these new steroids as photoaffinity labels of zero length is discussed.
