Check Digit Verification of cas no

The CAS Registry Mumber 99056-81-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,0,5 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 99056-81:
(7*9)+(6*9)+(5*0)+(4*5)+(3*6)+(2*8)+(1*1)=172
172 % 10 = 2
So 99056-81-2 is a valid CAS Registry Number.

Optimised synthesis of diamino-triazinylmethyl benzoates as inhibitors of Rad6B ubiquitin conjugating enzyme

Kothayer, Hend,Morelli, Matteo,Brahemi, Ghali,Elshanawani, Abdalla A.,Abu Kull, Mansour E.,El-Sabbagh, Osama I.,Shekhar, Malathy P.V.,Westwell, Andrew D.

Recently, we have identified the first inhibitors of Rad6B, an E2 enzyme essential for post-replication DNA repair and a potential new drug target for the treatment of breast cancer. We report two newly optimised synthetic routes to our [4-amino-6-(phenylamino)-1,3,5-triazin-2-yl]methyl 4-nitrobenzoate target compounds TZ8 and TZ9 with general applicability for further structure-activity relationship studies around this pharmacophore. The key step involved the condensation/cyclisation between phenylbiguanide and either ethyl bromoacetate or dimethyloxalate in good yield.
