1198330-46-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1198330-46-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,8,3,3 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1198330-46:
(9*1)+(8*1)+(7*9)+(6*8)+(5*3)+(4*3)+(3*0)+(2*4)+(1*6)=169
169 % 10 = 9
So 1198330-46-9 is a valid CAS Registry Number.

Synthesis and reactions of some new thieno[2,3-c]pyridazine derivatives
Al-Kamali, Ahmed S. N.
experimental part, p. 1812 - 1824 (2010/02/28)
The alkylation of 4-cyano-5,6-dimethylpyridazin-3(2H)-thione 3 with some halo compounds gave the S-alkylated products 4a-c, which upon treatment with ethanolic sodium ethoxide afforded the cyclized thienopyridazines 5a-c as products. Pyridazothienotriazin
