Check Digit Verification of cas no

The CAS Registry Mumber 354988-04-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,4,9,8 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 354988-04:
(8*3)+(7*5)+(6*4)+(5*9)+(4*8)+(3*8)+(2*0)+(1*4)=188
188 % 10 = 8
So 354988-04-8 is a valid CAS Registry Number.

Synthesis of new chiral 4,5,6,7-tetrahydro[1,2,3]triazolo[1,5-a]pyrazines from α-amino acid derivatives under mild conditions

Mohapatra, Debendra K.,Maity, Pradip K.,Gonnade, Rajesh G.,Chorghade, Mukund S.,Gurjar, Mukund K.

, p. 1893 - 1896 (2007)

A practical and efficient regioselective synthesis of several new chiral 4,5,6,7-tetrahydro[1,2,3]triazolo[1,5-a]pyrazines is described from α-amino acid derivatives following intramolecular 'click' reaction as the key step. The method obviates product pu
