Check Digit Verification of cas no

The CAS Registry Mumber 106932-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,9,3 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 106932-99:
(8*1)+(7*0)+(6*6)+(5*9)+(4*3)+(3*2)+(2*9)+(1*9)=134
134 % 10 = 4
So 106932-99-4 is a valid CAS Registry Number.

CYCLIZATION AND REARRANGEMENT OF DITERPENOIDS. SYNTHESIS OF Δ12 - AND Δ13(14)-ISO-20-DEOXYLUTEONES

Vlad, P. F.,Ungur, N. D.

, p. 752 - 759 (1985)

Δ12- and Δ13(14)-Iso-20-deoxyluteones have been synthesized from 13E- and 13Z- bicyclogeranylgeranylacetones.The latter were reduced to the corresponding alcohols, which were acetylated, and the acetates obtained were cyclized with fluorosulfonic acid in nitropropane.The reaction product was saponified to a mixture of tricyclic alcohols which were oxidized with the chromium trioxide-pyridine complex to a mixture of Δ12- and Δ13(14)-iso-20-deoxyluteones and this was separated chromatographically.
