Check Digit Verification of cas no

The CAS Registry Mumber 1101181-32-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,1,1,8 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1101181-32:
(9*1)+(8*1)+(7*0)+(6*1)+(5*1)+(4*8)+(3*1)+(2*3)+(1*2)=71
71 % 10 = 1
So 1101181-32-1 is a valid CAS Registry Number.

An enantioselective total synthesis of tubulysin V

Tao, Wei,Zhou, Wen,Zhou, Zhu,Si, Chang-Mei,Sun, Xun,Wei, Bang-Guo

, p. 5928 - 5933 (2016)

Tubulysin V has been enantioselectively synthesized from the units of dipeptide 23, Tuv and Tup. The features of this synthetic strategy is included three portions, the Tuv fragment 17 was diastereoselectively synthesized from the D-malic acid, the stereocenters of the Tup unit was constructed by the asymmetric reduction as well as methylation, and the epimerization for several known methods was successfully avoided by condensation of fragment 19 with 24, and by deprotection with hydrogenation.
