Check Digit Verification of cas no

The CAS Registry Mumber 457050-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,7,0,5 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 457050-40:
(8*4)+(7*5)+(6*7)+(5*0)+(4*5)+(3*0)+(2*4)+(1*0)=137
137 % 10 = 7
So 457050-40-7 is a valid CAS Registry Number.

An improved methodology for the preparation of 4,7-dimethoxy-1H- benzimidazole, a key intermediate in the synthesis of 1-alkyl-1H-benzimidazole- 4,7-diones

Taleb, Abbass,Alvarez, Frederic,Nebois, Pascal,Walchshofer, Nadia

, p. 111 - 114 (2006)

We reported an optimized process for the preparation of key intermediate, 4,7-dimethoxy-1H-benzimidazole, from commercially available 1,4-dimethoxybenzene (Overall yield 52%). We successfully applied this methodology to an improved synthesis of 1-benzyl-1

Benzimidazole-4,7-diones as inhibitors of protozoal (Toxoplasma gondii) purine nucleoside phosphorylase

Alvarez, Frédéric,Ghérardi, Arnaud,Nebois, Pascal,Sarciron, Marie-Elizabeth,Pétavy, Anne-Fran?oise,Walchshofer, Nadia

, p. 977 - 979 (2007/10/03)

Benzimidazole-4,7-diones derivatives substituted at 1- and/or 2-position have been synthetized and tested as inhibitors of purine nucleoside phosphorylase (PNP), isolated from two strains of Toxoplasma gondii (RH and ME 49). They were identified as inhibi
