Check Digit Verification of cas no

The CAS Registry Mumber 76758-15-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,7,5 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76758-15:
(7*7)+(6*6)+(5*7)+(4*5)+(3*8)+(2*1)+(1*5)=171
171 % 10 = 1
So 76758-15-1 is a valid CAS Registry Number.

Synthesis of N-(Tosylmethyl)carbodiimides and Their Application in the Synthesis of 2-Amino-1,3-oxazoles from Aldehydes

Leusen, Albert M. van,Jeuring, Hans J.,Wildeman, Jurjen,Nispen, Simon P. J. M. van

, p. 2069 - 2072 (2007/10/02)

A series of N-(tosylmethyl)carbodiimides (TosCH2N=C=NR1, 3) have been prepared from the corresponding thioureas.Carbodiimides 3 with R1 = triphenylmethyl or tert-butyl are useful synthons in a new one-step synthesis of 2-(alkylamino)-1,3-oxazoles 10 from aromatic aldehydes.Acid-induced removal of the triphenylmethyl group from 10 gives 2-amino-1,3-oxazoles (11).
