108221-75-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108221-75-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,2,2 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 108221-75:
(8*1)+(7*0)+(6*8)+(5*2)+(4*2)+(3*1)+(2*7)+(1*5)=96
96 % 10 = 6
So 108221-75-6 is a valid CAS Registry Number.

A Facile Procedure for the Synthesis of Condensed Dipyrazoles
Matsugo, S.,Takamizawa, A.
, p. 866 - 868 (2007/10/02)
Utilizing the tautomeric property of 1,3-disubstituted-4,5-dihydropyrazol-5-ones 1, a facile one-pot synthesis of highly substituted 1,4,6,9-tetrahydro-4,9-methano-1,5-dioxocindipyrazoles 2 has been achieved.
