Check Digit Verification of cas no

The CAS Registry Mumber 178153-04-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,1,5 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 178153-04:
(8*1)+(7*7)+(6*8)+(5*1)+(4*5)+(3*3)+(2*0)+(1*4)=143
143 % 10 = 3
So 178153-04-3 is a valid CAS Registry Number.

Synthesis of a novel chiral 1, 3-Benzoxazinone auxiliary and its application to highly diastereoselective aldol reaction

Miyake, Tsutomu,Seki, Masahiko,Nakamura, Yoshinori,Ohmizu, Hiroshi

, p. 3129 - 3132 (2007/10/03)

Condensation of 1-menthone with salicylamide followed by isomerization of the adduct withDBU afforded a novel chiral 1, 3-benzoxazinone auxiliary, the usefulness of which was demonstrated by highly diastereoselective aldol reaction with aldehydes. Copyright
