Check Digit Verification of cas no

The CAS Registry Mumber 201029-45-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,0,2 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 201029-45:
(8*2)+(7*0)+(6*1)+(5*0)+(4*2)+(3*9)+(2*4)+(1*5)=70
70 % 10 = 0
So 201029-45-0 is a valid CAS Registry Number.

Preparation of (Cp * ) {C5Me4CH2B(C6F5) 3}ZrPh, a novel zwitterionic single-component alkene polymerisation catalyst

Song, Xuejing,Bochmann, Manfred

, p. 597 - 600 (1997)

B(C6F5)3 reacts with the fulvene complex (pentamethylcyclopentadienyl)(π-η5: σ-η1-tetramethylfulvene)phenylzirconium (Cp * FvZrPh) (I) selectively under attack at the fulvene-CH2 group to form the highly sensitive zwitterionic complex (Cp * ){(C5Me4CH2-B(C6F5)3}ZrPh (II). Mixtures of I with either B(C6F5)3 or [CPh3][B(C6F5)4] are highly active for the polymerisation of ethene over a wide range of temperatures.
