Check Digit Verification of cas no
The CAS Registry Mumber 101391-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,3,9 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 101391-45:
(8*1)+(7*0)+(6*1)+(5*3)+(4*9)+(3*1)+(2*4)+(1*5)=81
81 % 10 = 1
So 101391-45-1 is a valid CAS Registry Number.

1-BROMOBICYCLOBUTANES AND STRONG BASES: PRODUCTS AND MECHANISM
Dueker, Axel,Szeimies, Guenter
, p. 3555 - 3558 (1985)
Treatment of the bromobicyclobutanes 4a - c with LDA led to the formation of the 1,2,3-butatrienes 6 which were isomerized by excess base to the alkynes 8.Reaction of 4c with LDA afforded 8d, indicating that bicyclobut-1(3)-ene 5 was not an intermediate.
