402958-24-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 402958-24-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,2,9,5 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 402958-24:
(8*4)+(7*0)+(6*2)+(5*9)+(4*5)+(3*8)+(2*2)+(1*4)=141
141 % 10 = 1
So 402958-24-1 is a valid CAS Registry Number.

Telaprevir intermediate preparation method

-

, (2017/08/31)

The invention discloses a telaprevir intermediate preparation method. A telaprevir intermediate is a formula I compound, and a reaction route is as shown in the specification, wherein R is selected from C1-C4 alkyl groups, R1 is selected from hydrogen, C1-C8 alkyl groups, C1-C8 alkoxy groups, C6-C12 aryl groups, alkyl sulfonyl, C6-C12 aryl sulfonyl groups or substituted C6-C12 aryl sulfonyl groups, and P is an amino protection group. The method has advantages of simplicity in operation, safety, freeness of pollution and special requirements on equipment, low production cost, high yield and the like, is suitable for large-scale production and has a high practical value in realization of telaprevir industrialization.
