Check Digit Verification of cas no

The CAS Registry Mumber 1364740-54-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,6,4,7,4 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1364740-54:
(9*1)+(8*3)+(7*6)+(6*4)+(5*7)+(4*4)+(3*0)+(2*5)+(1*4)=164
164 % 10 = 4
So 1364740-54-4 is a valid CAS Registry Number.

Practical synthesis of a benzophenone-based NNRT inhibitor of HIV-1

Wang, Xiao-Jun,Zhang, Li,Sun, Xiufeng,Lee, Heewon,Krishnamurthy, Dhileepkumar,O'Meara, Jeff A.,Landry, Serge,Yoakim, Christiane,Simoneau, Bruno,Yee, Nathan K.,Senanayake, Chris H.

, p. 561 - 566 (2012/07/03)

A convergent synthesis of NNRTI 1 is described. The key step involves a direct coupling of acid chloride 4 with Grignard reagent 11 in the presence of bis[2-(N,N-dimethylamino)ethyl] ether that moderates the reactivity of the Grignard reagent to give benzophenone 7. An efficient 2-step process for the preparation of 2-fluoro-3-methyl-4-aminobenzoic acid (3) is also described.
