Check Digit Verification of cas no
The CAS Registry Mumber 27207-08-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,2,0 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 27207-08:
(7*2)+(6*7)+(5*2)+(4*0)+(3*7)+(2*0)+(1*8)=95
95 % 10 = 5
So 27207-08-5 is a valid CAS Registry Number.

The reaction of 5-amino-1,3-diphenylpyrazole with benzaldehyde gives 5-benzylideneamino-1,3-diphenylpyrazole, wich then undergoes cyclization with mercaptoacetic acid to give 1,3,4-triphenyl-1H-pyrazolothiazepin-7-one.
