Check Digit Verification of cas no

The CAS Registry Mumber 134927-18-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,2 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134927-18:
(8*1)+(7*3)+(6*4)+(5*9)+(4*2)+(3*7)+(2*1)+(1*8)=137
137 % 10 = 7
So 134927-18-7 is a valid CAS Registry Number.

Oxidation of triterpenoids: Part IX - Oxidation of lupanone with selenium dioxide in t-butanol

Pradhan, Bhim Prasad,Chakraborty, Satyajit,Subba, Gyan Chandra,Weyerstahl, Peter

, p. 390 - 394 (2007/10/02)

Lupanone (1) on prolonged heating with selenium dioxide in t-butanol furnishes six products, lup-1-en-3-one (2), lup-1(2)-en-3-one-2-selenide (3), lup-1(2)-en-3-one-2-bis-selenide (4), 3-carboxy-1β,3α-dihydroxy-A-norlupane (5), A-norlupan anhydride (6), 1-hydroxylupan anhydride (7) and 1-hydroxy-A-norlup-2-carb-4-olide (8).Oxidation of 3/4 with alkaline H2O2 affords 1α,2α-epoxy-lup-3-one (9).The structures of the compounds have been established on the basis of analytical and spectral data.
