The CAS Registry Mumber 97861-65-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,8,6 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 97861-65:
(7*9)+(6*7)+(5*8)+(4*6)+(3*1)+(2*6)+(1*5)=189
189 % 10 = 9
So 97861-65-9 is a valid CAS Registry Number.

An efficient approach to 2-bromoalken-3-ols by regioselective bromohydroxylation reaction of simple allenes with NBS

Kong, Wangqing,Guo, Binjie,Fu, Chunling,Ma, Shengming

experimental part, p. 2278 - 2285 (2011/06/19)

A regioselective bromohydroxylation reaction of simple allenes affording 2-bromoalken-3-ols in moderate-to-good yields has been developed by using NBS as the electrophilic reagent in a mixture of 1,4-dioxane/H2O (1:1) at room temperature. Throu
