113968-82-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113968-82-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,9,6 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 113968-82:
(8*1)+(7*1)+(6*3)+(5*9)+(4*6)+(3*8)+(2*8)+(1*2)=144
144 % 10 = 4
So 113968-82-4 is a valid CAS Registry Number.

THE SYNTHESIS OF 2-PHENYL-3-NITRO-3,4-DIHYDRO-2H-1-BENZOPYRANS
Varma, Rajender S.,Kadkhodayan, Miryam,Kabalka, George W.
, p. 1647 - 1652 (2007/10/02)
A series of 3-nitrochromans, including a 3-phenyl-2-nitrodihydronaphthopyran, were synthesized in good yields by selective reduction of the corresponding 3-nitrochromenes using sodium borohydride in methanolic tetrahydrofuran.
