850404-86-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 850404-86-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,4,0 and 4 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 850404-86:
(8*8)+(7*5)+(6*0)+(5*4)+(4*0)+(3*4)+(2*8)+(1*6)=153
153 % 10 = 3
So 850404-86-3 is a valid CAS Registry Number.

A convergent and enantioselective total synthesis of (+)-leucascandrolide (1) was accomplished in 17 steps. Central to this synthesis is the rapid and efficient integration of the bispyran moiety into 1 using two consecutive [4 + 2] annulation reactions b
