1237706-65-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1237706-65-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,7,7,0 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1237706-65:
(9*1)+(8*2)+(7*3)+(6*7)+(5*7)+(4*0)+(3*6)+(2*6)+(1*5)=158
158 % 10 = 8
So 1237706-65-8 is a valid CAS Registry Number.

Synthesis and properties of dimeric octaalkylporphyrins with a polyether linker
Mal'tseva,Churakhina,Mamardashvili
experimental part, p. 444 - 449 (2010/09/20)
Octaalkylporphyrin dimers with a polyether linker were synthesized, and their physicochemical properties were studied. Specific response of the tetrapyrrole chromophore to complexation with potassium cation at the polyether moiety was examined.
