Check Digit Verification of cas no

The CAS Registry Mumber 21012-53-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,1 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21012-53:
(7*2)+(6*1)+(5*0)+(4*1)+(3*2)+(2*5)+(1*3)=43
43 % 10 = 3
So 21012-53-3 is a valid CAS Registry Number.

An efficient one pot synthesis of new indanopyrazoline and indanopyrazole derivatives

Jelizi, Hanene,Rammah, Mohamed M.,Askri, Moheddine,El Baker Rammah, Mohamed,Ciamala, Kabula,Monnier-Jobe, Karin

, p. 268 - 273 (2012/05/05)

Synthesis of a series of novel fused pyrazolines and pyrazoles has been accomplished in good yields by regioand diastereoselective 1,3-dipolar cycloaddition of enamines of indan-1-one 1a-c towards C-aryl-N- phenylnitrilimines 2df. The structure of the cycloadducts was elucidated by 1D and 2D NMR studies.

Conversion des Cis- et Trans-Pyrazolines en Pyrazoles Sur Support Mineral Impregne de Nitrate Ferrique ou Cuivrique

Bougrin, Khalid,Soufiaoui, Mohamed,Yazidi, Mohamed El

, p. 4065 - 4068 (2007/10/02)

Pyrazoles are prepared from cis- and trans-pyrazolines with good yield in dichloromethane under mild reaction conditions using the inexpensive clay-supported iron (III) nitrate "Clayfen" or copper (II) nitrate "Claycop".
