74204-87-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74204-87-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,0 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74204-87:
(7*7)+(6*4)+(5*2)+(4*0)+(3*4)+(2*8)+(1*7)=118
118 % 10 = 8
So 74204-87-8 is a valid CAS Registry Number.

, p. 169 - 174 (2007/10/02)
Thiocarbamoyl derivatives of N-phenylpyrazolines are converted under the influence of acidic agents to mixture of tetrahydropyrimidobenzothiazoles and 2-imino-3-aminoalkylbenzothiazoles and not only to tetrahydropyrimidobenzothiazoles, as previousl
