Check Digit Verification of cas no

The CAS Registry Mumber 74693-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,9 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74693-77:
(7*7)+(6*4)+(5*6)+(4*9)+(3*3)+(2*7)+(1*7)=169
169 % 10 = 9
So 74693-77-9 is a valid CAS Registry Number.

Attempted spirocyclisation of tricarbonylmalonate>iron hexafluorophosphate (4) and tricarbonyliron hexafluorophosphate (11) to the desired spirodecane derivatives (5) and (12) failed under a variety of mild conditions.Spirocyclisation of tricarbonyliron hexafluorophosphate (25) occurs smoothly and rapidly at -78 ged C to give the tricarbonylundeca-7,9-diene-1-carboxylate)>iron diastereoisomers (26) and (27).
