213815-41-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213815-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,8,1 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 213815-41:
(8*2)+(7*1)+(6*3)+(5*8)+(4*1)+(3*5)+(2*4)+(1*1)=109
109 % 10 = 9
So 213815-41-9 is a valid CAS Registry Number.

, p. 6373 - 6376 (2007/10/03)
Stereoselective synthesis of the H ring of gambierol was achieved from 2-deoxy-D-ribose by using the intramolecular reaction of allylstannane with aldehyde as a key step. Modified Stille coupling was successfully applied for the construction of the triene
