Check Digit Verification of cas no

The CAS Registry Mumber 89731-29-3 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 9 respectively.
Calculate Digit Verification of CAS Registry Number 89731-29:
(7*8)+(6*9)+(5*7)+(4*3)+(3*1)+(2*2)+(1*9)=173
173 % 10 = 3
So 89731-29-3 is a valid CAS Registry Number.

PYRANOSIDIC HOMOLOGATION: PART II: EXTENDING THE CARBOHYDRATE TEMPLATE VIA VICINAL (SECONDARY) HYDROXYLS

Magdzinski, Leon,Cweiber, Bruce,Fraser-Reid, Bert

, p. 5823 - 5826 (1983)

The oxyrane ring of the dianhydro sugar (3b) is opened regioselectively by the dianion (4b), and reaction of the derived allylic alcohol (7b) with trifluoroacetic acid gives the oxa-cis-decalin (8b), which can be epoxidised selectively from the endo or ex
