Check Digit Verification of cas no

The CAS Registry Mumber 940934-47-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,0,9,3 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 940934-47:
(8*9)+(7*4)+(6*0)+(5*9)+(4*3)+(3*4)+(2*4)+(1*7)=184
184 % 10 = 4
So 940934-47-4 is a valid CAS Registry Number.

Palladium-catalyzed nucleophilic substitution of diarylmethyl carbonates with malonate carbanions

Kuwano, Ryoichi,Kusano, Hiroki

, p. 528 - 529 (2008/02/10)

The nucleophilic substitution of diarylmethyl carbonates with malonate carbanions proceeded in the presence of [Pd(π-C3H 5)(cod)]BF4-Cy-Xantphos, giving the desired (diarylmethyl)malonates in up to 90% yield. The yield was extremely affected by choice of the phosphine ligand. Copyright
