Check Digit Verification of cas no

The CAS Registry Mumber 931854-75-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,1,8,5 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 931854-75:
(8*9)+(7*3)+(6*1)+(5*8)+(4*5)+(3*4)+(2*7)+(1*5)=190
190 % 10 = 0
So 931854-75-0 is a valid CAS Registry Number.

High-load, oligomeric dichlorotriazine: A versatile ROMP-derived reagent and scavenger

Rolfe, Alan,Probst, Donald A.,Volp, Kelly A.,Omar, Iman,Flynn, Daniel L.,Hanson, Paul R.

, p. 8785 - 8790 (2008)

(Chemical Equation Presented) A new high-load, soluble oligomeric dichlorotriazine (ODCT) reagent derived from ring-opening metathesis polymerization (ROMP) is reported as an effective coupling reagent, scavenger of nucleophilic species, and activator of DMSO for the classic Swern oxidations. Two variants of this reagent 2GODCT 4 and 1GODCT 16, possessing theoretical loads of 5.3 and 7.3 mmol/g, respectively, have been synthesized. Preparation was accomplished via simple synthetic protocols affording free flowing powders, amenable for large-scale production. Removal of the spent oligomeric reagent was achieved via either precipitation of the spent reagent or simple filtration utilizing a silica SPE, followed by solvent removal, to deliver products in excellent yield and purity. In addition, the corresponding norbornenyl monomer 3 was successfully demonstrated in a couple-ROMP-filter protocol utilizing in situ polymerization, achieving comparable results versus the corresponding oligomeric variant.
