334706-39-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 334706-39-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,4,7,0 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 334706-39:
(8*3)+(7*3)+(6*4)+(5*7)+(4*0)+(3*6)+(2*3)+(1*9)=137
137 % 10 = 7
So 334706-39-7 is a valid CAS Registry Number.

Synthetic studies toward the microtubule-stabilizing agent laulimalide: Synthesis of the C15-C28 fragment
Messenger,Davidson, Bradley S.
, p. 801 - 803 (2007/10/03)
The C15-C28 fragment of the paclitaxel-like antimicrotubule agent laulimalide has been synthesized in 12 linear steps with an overall yield of 14%. The methyldihydropyran ring of the side chain was efficiently prepared using ring-clo
