Check Digit Verification of cas no

The CAS Registry Mumber 1309569-21-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,5,6 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1309569-21:
(9*1)+(8*3)+(7*0)+(6*9)+(5*5)+(4*6)+(3*9)+(2*2)+(1*1)=168
168 % 10 = 8
So 1309569-21-8 is a valid CAS Registry Number.

, p. 4473 - 4475 (2017)

An efficient method for the synthesis of 5-SF5 substituted indazoles from commercially available 4-nitro-(pentafluorosulfanyl)benzene through vicarious nucleophilic substitution of hydrogen (VNS) reaction, reduction of nitro group and cyclizati

Preparation of SF5 aromatics by vicarious nucleophilic substitution reactions of nitro(pentafluorosulfanyl)benzenes with carbanions

Beier, Petr,Pastyrikova, Tereza,Iakobson, George

, p. 4781 - 4786 (2011/07/07)

Vicarious nucleophilic substitutions (VNS) of hydrogen in 1-nitro-4-(pentafluorosulfanyl)benzene with carbanions provide 2-substituted 1-nitro-4-(pentafluorosulfanyl)benzenes in good to high yields. VNS of 1-nitro-3-(pentafluorosulfanyl)benzene gives a mi
