Check Digit Verification of cas no

The CAS Registry Mumber 951167-15-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,1,1,6 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 951167-15:
(8*9)+(7*5)+(6*1)+(5*1)+(4*6)+(3*7)+(2*1)+(1*5)=170
170 % 10 = 0
So 951167-15-0 is a valid CAS Registry Number.

Spirobicyclic diamines. Part 3: Synthesis and metal complexation of proline-derived [4.4]-spirodiamines

Kelleher, Fintan,Kelly, Sinead,McKee, Vickie

, p. 9235 - 9242 (2008/02/10)

The syntheses of racemic and homochiral [4.4]-spirolactams, starting from l-proline, in good yields are described. Reduction of the lactam carbonyl group of spirolactams, containing chiral substituents on the lactam nitrogen, with lithium aluminium hydride, gives?a series of homochiral [4.4]-spirodiamines. The crystal structure of one of these spirodiamines on complexation with zinc chloride was obtained. Interestingly it showed a hydrogen-bonded dimeric structure, where the monomers are diastereoisomeric diamines.
