Check Digit Verification of cas no

The CAS Registry Mumber 85703-92-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,7,0 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 85703-92:
(7*8)+(6*5)+(5*7)+(4*0)+(3*3)+(2*9)+(1*2)=150
150 % 10 = 0
So 85703-92-0 is a valid CAS Registry Number.

New Heterocyclic Systems from Electrophilic Cyclopropenes and N-Nucleophiles

Duerr, Heinz,Gross, Hubert,Hauck, Gerd

, p. 856 - 861 (2007/10/02)

Reaction of the electron-deficient spirocyclopropene 1 with electron-rich heterocycles affords betaine 4a, the five-membered heterocycles 5b - d, and the spiroheterocycles 6a - c.Spectral data as well as a mechanism for the formation of adducts are presented.
