Check Digit Verification of cas no

The CAS Registry Mumber 66213-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,2,1 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 66213-20:
(7*6)+(6*6)+(5*2)+(4*1)+(3*3)+(2*2)+(1*0)=105
105 % 10 = 5
So 66213-20-5 is a valid CAS Registry Number.

Iridoids, XXII. - Glucosidation of Hemiacetals. - Highly Stereoselective Synthesis of Iridoid Glucosides

Tietze, Lutz F.,Fischer, Roland,Remberg, Gerd

, p. 971 - 976 (2007/10/02)

Reaction of the racemic iridoid aglucone acetates 9d-12d with the trimethylsilyl β-glucopyranoside 4a in the presence of catalytic amounts of trimethylsilyl trifluoromethanesulfonate (7) in acetonitrile or liquid sulfur dioxide at -30 deg C and -50 deg C, respectively, followed by solvolysis gives in excellent yields nearly exclusively the β-glucosides 9g and 11g.Glucosidation of the enantiomerically pure acetates 9d/10d affords the β-glucoside 9g.In a similar way, the biosynthetical key intermediate loganin (1) is obtained from 16a in 60 percent yield.
