Check Digit Verification of cas no

The CAS Registry Mumber 718605-04-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,8,6,0 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 718605-04:
(8*7)+(7*1)+(6*8)+(5*6)+(4*0)+(3*5)+(2*0)+(1*4)=160
160 % 10 = 0
So 718605-04-0 is a valid CAS Registry Number.

Chemiluminescence quenching of pteroic acid-N-sulfonyl-acridinium-9- carboxamide conjugates by folate binding protein

Adamczyk, Maciej,Fino, James R.,Mattingly, Phillip G.,Moore, Jeffrey A.,Pan, You

, p. 2313 - 2317 (2004)

N10-Trifluoroacetylpteroic acid was conjugated to chemiluminescent N-sulfonylacridinium-9-carboxamide labels at the N10 or 9-position carboxamide. Upon binding to folate binding protein the light output of the N10 derivative (9) was quenched up to 62% upon triggering with basic peroxide, while the 9-position carboxamide conjugate (7) was quenched only 12%. The utility of this effect was demonstrated in a model homogeneous chemiluminescent assay for folic acid.
