900503-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 900503-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,0,5,0 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 900503-45:
(8*9)+(7*0)+(6*0)+(5*5)+(4*0)+(3*3)+(2*4)+(1*5)=119
119 % 10 = 9
So 900503-45-9 is a valid CAS Registry Number.

, p. 555 - 560 (2006)
The synthesis of a new bicyclic vinyl boronate (5) was accomplished from N-Boc-nortropinone (6) in two steps. The Suzuki-Miyaura coupling of 5 to a variety of aryl bromides and triflates afforded 3-aryl-8-azabicyclo[3.2.1]oct-2- enes in good yields by adj
