Check Digit Verification of cas no

The CAS Registry Mumber 85339-41-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,3,3 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 85339-41:
(7*8)+(6*5)+(5*3)+(4*3)+(3*9)+(2*4)+(1*1)=149
149 % 10 = 9
So 85339-41-9 is a valid CAS Registry Number.

THE STEREOSELECTIVE SYNTHESIS OF 2,3-CIS-DIHYDROXY-γ-BUTYROLACTONES BY THE OXIDATION OF γ-BUTENOLIDES WITH KMnO4-CROWN ETHER

Mukaiyama, Teruaki,Tabusa, Fujio,Suzuki, Keisuke

, p. 173 - 174 (2007/10/02)

Oxidation of γ-butenolides was effected by KMnO4-crown ether to afford the corresponding 2,3-cis-dihydroxy-γ-butyrolactones in high yields.High stereoselectivity was observed in cases when bulky substituents were introduced at the γ-position of the buteno
