190505-36-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 190505-36-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,5,0 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 190505-36:
(8*1)+(7*9)+(6*0)+(5*5)+(4*0)+(3*5)+(2*3)+(1*6)=123
123 % 10 = 3
So 190505-36-3 is a valid CAS Registry Number.

A New Approach to the Synthesis of Cortical Steroids
Shih, Ing-Lung,Hendrickson, James B.
, p. 133 - 140 (2007/10/03)
A new bondset for cortical steroid synthesis is developed from the dual concepts of convergent assembly and multiple construction. A short synthesis on this bondset is presented in which the final bond construction by electrocyclization took an unwanted c
