89731-22-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89731-22-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,3 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89731-22:
(7*8)+(6*9)+(5*7)+(4*3)+(3*1)+(2*2)+(1*2)=166
166 % 10 = 6
So 89731-22-6 is a valid CAS Registry Number.

PYRANOSIDIC HOMOLOGATION: PART I: EXTENDING THE CARBOHYDRATE TEMPLATE VIA C6 AND C4
Molino, Bruce F.,Magdzinski, Leon,Fraser-Reid, Bert
, p. 5819 - 5822 (2007/10/02)
The aldehyde (6) reacts with ylid (3b) to give (7) as a 4:1 Z/E mixture which, upon methanolysis under catalysis by pyridinium p-toluenesulfonate (PPTS), affords the bispyranoside (5a) as single anomer.
