Check Digit Verification of cas no

The CAS Registry Mumber 1428672-06-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,6,7 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1428672-06:
(9*1)+(8*4)+(7*2)+(6*8)+(5*6)+(4*7)+(3*2)+(2*0)+(1*6)=173
173 % 10 = 3
So 1428672-06-3 is a valid CAS Registry Number.

Enantio- and diastereoselective synthesis of N-acetyl dihydrotetrafibricin methyl ester

Nuhant, Philippe,Roush, William R.

supporting information, p. 5340 - 5343 (2013/05/22)

A highly diastereoselective synthesis of N-acetyl dihydrotetrafibricin methyl ester (34) is described. The synthesis features three enantioselective double allylboration reactions and an intramolecular hydrosilylation/Fleming- Tamao oxidation sequence to establish seven of the hydroxy-bearing stereocenters of 34. Especially noteworthy is the fragment-assembly double allyboration reaction of 2 and 7 using reagent 3, which provides the advanced intermediate 6 with >20:1 diastereoselectivity.
