Check Digit Verification of cas no

The CAS Registry Mumber 140231-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,2,3 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 140231-98:
(8*1)+(7*4)+(6*0)+(5*2)+(4*3)+(3*1)+(2*9)+(1*8)=87
87 % 10 = 7
So 140231-98-7 is a valid CAS Registry Number.

On palladium catalyzed cyclizations to medium sized carbocycles

Trost, Barry M.,Vos, Beverly A.,Brzezowski, Christine M.,Martina, Daniel P.

, p. 717 - 720 (2007/10/02)

With proper choice of Pd(O) catalyst, especially by employment of a novel bidentate phosphite ligand, and substitution pattern of substrate, eight and nine membered carbocyclic ring formation dominates the normally much more favorable six and seven membered ring formation.
