Check Digit Verification of cas no
The CAS Registry Mumber 129103-94-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,0 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129103-94:
(8*1)+(7*2)+(6*9)+(5*1)+(4*0)+(3*3)+(2*9)+(1*4)=112
112 % 10 = 2
So 129103-94-2 is a valid CAS Registry Number.

A Complex Induced Proximity Effect in the Anionic Fries Rearrangement of o-Iodophenyl Benzoates: Synthesis of Dihydro-O-methylsterigmatocystin and Other Xanthones
Horne, Stephen,Rodrigo, Russell
, p. 4520 - 4522 (2007/10/02)
The success of an anionic Fries rearrangement, used to synthesise dihydro-O-methylsterigmatocystin and other xanthones, is dependent on the presence of a remote methoxyl substituent.
