Check Digit Verification of cas no

The CAS Registry Mumber 1312799-20-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,7,9 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1312799-20:
(9*1)+(8*3)+(7*1)+(6*2)+(5*7)+(4*9)+(3*9)+(2*2)+(1*0)=154
154 % 10 = 4
So 1312799-20-4 is a valid CAS Registry Number.

In situ generated (Hypo)iodite catalysts for the direct α-oxyacylation of carbonyl compounds with carboxylic acids

Uyanik, Muhammet,Suzuki, Daisuke,Yasui, Takeshi,Ishihara, Kazuaki

supporting information; experimental part, p. 5331 - 5334 (2011/07/08)

It′s the iodine: The intra- and intermolecular title reaction is catalyzed by an in situ generated ammonium (hypo)iodite species. Either H 2O2 or tert-butyl hydroperoxide (TBHP) can be used as an environmentally benign oxidant and a wide range of substrates react to give the corresponding α-acyloxycarbonyl compounds in good to excellent yields.
