Check Digit Verification of cas no
The CAS Registry Mumber 867350-37-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,7,3,5 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 867350-37:
(8*8)+(7*6)+(6*7)+(5*3)+(4*5)+(3*0)+(2*3)+(1*7)=196
196 % 10 = 6
So 867350-37-6 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
