111802-47-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111802-47-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,8,0 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 111802-47:
(8*1)+(7*1)+(6*1)+(5*8)+(4*0)+(3*2)+(2*4)+(1*7)=82
82 % 10 = 2
So 111802-47-2 is a valid CAS Registry Number.

Suppression of the Mattox Rearrangement of 16α-Cyanoprednisolones in Acid: Synthesis of Methyl 16α-Prednisolonecarboxylates
Yuo, Zhengqing,Khalil, Mounir A.,Ko, Dong-Hoon,Lee, Henry J.
, p. 3303 - 3306 (2007/10/02)
Prednisolone derivatives with a 16α-methyl carboxylate group were synthesized by a novel procedure of 1,3-dipole addition of fulminic acid to 21-acetyloxy-11β-hydroxy-3,20-dioxo-1,4,16-pregnatriene, followed by base-catalyzed ring opening of the resulting
