Check Digit Verification of cas no

The CAS Registry Mumber 130645-19-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,4 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 130645-19:
(8*1)+(7*3)+(6*0)+(5*6)+(4*4)+(3*5)+(2*1)+(1*9)=101
101 % 10 = 1
So 130645-19-1 is a valid CAS Registry Number.

, (2008/06/13)

A chelate formed between Eu3+, Tb3+, Dy3+ and Sm3+ and a compound having the formula STR1 where A1-6 are single carbon or nitrogen atoms; n=1 or 2; R1-6 is nothing when A is a nitrogen, and hydrogen or an organic group when A is a carbon; Z and Z' are selected among --N(CH2 CH2 COO-)2, --N(CH2 COO-)2, --N(CH2 OPO32-)2 and --N(CH2 PO32-)2 ;--species that --X--Y is a substituent replacing a hydrogen anywhere in the parent compound; and --X--Y represents an organic group containing no chelating heteroatom closer than four atoms from a chelating heteroatom in the parent compound and X is a stable bridge containing certain groups and Y is selected from (a) specified relative groups allowing coupling to other compounds and (b) residues of compounds participating in biospecific affinity reactions.
