57789-30-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57789-30-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,7,8 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 57789-30:
(7*5)+(6*7)+(5*7)+(4*8)+(3*9)+(2*3)+(1*0)=177
177 % 10 = 7
So 57789-30-7 is a valid CAS Registry Number.

Migrated Lupane Derivatives. Boron Trifluoride Etherate-catalyzed Backbone Rearrangement of 3α,4α- and 3β,4β-Epoxy-D:A-friedo-18β,19αH-lupanes and Solvent Effects

Yokoyama, Yasushi,Moriyama, Yoshihiko,Tsuyuki, Takahiko,Takahashi, Takeyoshi

, p. 234 - 239 (2007/10/02)

Backbone rearrangements of 3α,4α- and 3β,4β-epoxy-D:A-friedo-18β,19αH-lupanes catalyzed by boron trifluoride etherate gave 18β,19αH-lup-12-en-3-ols, lup-18-en-3-ols, and lup-19-en-3-ols besides known D:B-friedo-18β,19αH-lup-5-en-3-ols and -5(10)-en-3-ols.D:B-Friedo-18β,19αH-lup-1(10)-en-3α-ol and 3β,10β-epoxy-D:B-friedo-18β,19αH-lupane were also obtained from α- and β-epoxides, respectively.Solvent effects on these reactions were examined.
