41105-39-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 41105-39-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,1,0 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 41105-39:
(7*4)+(6*1)+(5*1)+(4*0)+(3*5)+(2*3)+(1*9)=69
69 % 10 = 9
So 41105-39-9 is a valid CAS Registry Number.

Optimization of the synthesis of phenanthrene-2- and -3-sulfonyl chlorides

Russkikh,Khokhrina,Shelkovnikov

experimental part, p. 547 - 551 (2012/06/29)

Sulfonation of phenanthrene with sulfuric acid, followed by neutralization with sodium hydroxide, gave a mixture of isomeric sodium phenanthrenesulfonates in an overall yield of 83%. Sodium phenanthrene- 2-, -3-, and -9-sulfonates were isolated in 17, 43, and 4% yield, respectively. Sulfonation of phenanthrene with ClSO3H or SO3 did not improve the yields of phenanthrene-2- and -3-sulfonic acids. Treatment of sodium phenanthrene-2- and -3-sulfonates with PCl5-POCl3 or SOCl2-DMF afforded the corresponding sulfonyl chlorides in 89 and 87 or 69 and 70% yield, respectively. Pure phenanthrene-2- and -3-sulfonyl chlorides were also synthesized in 27 and 51% yield by reaction of a mixture of 2- and 3-sulfonates with PCl5-POCl3. Pleiades Publishing, Ltd., 2012.
