Check Digit Verification of cas no

The CAS Registry Mumber 133391-80-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,9 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133391-80:
(8*1)+(7*3)+(6*3)+(5*3)+(4*9)+(3*1)+(2*8)+(1*0)=117
117 % 10 = 7
So 133391-80-7 is a valid CAS Registry Number.

Enantiomerically pure, crystalline 'anti'-aldols from N-acylbornanesultams: Aldolization and structure of intermediate t-butyldimethylsilyl-N,O-ketene acetal

Oppolzer, Wolfgang,Starkemann, Christian,Rodriguez, Ines,Bernardinelli, Gerald

, p. 61 - 64 (1991)

O-Silylation of N-propionylsultam 1 provides pure Z O-silyl-N,O-ketene acetal 2 which undergoes Lewis acid promoted addition of aromatic and aliphatic aldehydes to give diastereomerically pure, crystalline "anti" aldols 7 or their silylethers 3. Hydroperoxide-assisted hydrolysis/esterification of products 7 yields enantiomerically pure methoxycarbonyl aldols (11, 12, 13, 14).
