Check Digit Verification of cas no

The CAS Registry Mumber 120401-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,4,0 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 120401-41:
(8*1)+(7*2)+(6*0)+(5*4)+(4*0)+(3*1)+(2*4)+(1*1)=54
54 % 10 = 4
So 120401-41-4 is a valid CAS Registry Number.

STEREOCHEMICAL ASPECTS OF THE FORMATION OF DIASTEREOISOMERIC 3-ACETYL-2-(POLYACETOXYALKYL)-5-PHENYL-2,3-DIHYDRO-1,3,4-OXADIAZOLES

Somogyi, Laszlo

, p. 19 - 30 (2007/10/02)

The synthesis of D- and L-3-acetyl-2-- and 3-acetyl-2--5-phenyl-2,3-dihydro-1,3,4-oxadiazoles via cyclisation of the corresponding (O-acetylating conditions is described.The stereochemical aspects of the formation of C-2 epimeric oxadiazolines are discussed on the basis of optical rotation and n.m.r. data.The acetylation of methylglyoxal bis(benzoylhydrazone) (8) was found to give diastereoisomeric 1,3,4-oxadiazolines (12a and 12b) insteadof the bis(acetylbenzoylhydrazone) 9 claimed in the literature.
