90670-36-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90670-36-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,6,7 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90670-36:
(7*9)+(6*0)+(5*6)+(4*7)+(3*0)+(2*3)+(1*6)=133
133 % 10 = 3
So 90670-36-3 is a valid CAS Registry Number.

Practical synthesis of oligosaccharides. Partial synthesis of avermectin B(1a)
Nicolaou,Dolle,Papahatjis,Randall,Dolle
, p. 4189 - 4192 (2007/10/02)
A practical synthesis of oligosaccharides from phenylthio sugars via glycosyl fluorides is described. The new technology is applied to the synthesis of hexasaccharide 9 from a glucose derivative and avermectin B1a(11) from an avermectin B1
